John D. Ehrlichman was convicted by a jury of the United States District Court for the District of Columbia on one count of conspiracy to violate the civil rights of Dr. Louis Fielding, 18 U.S.C. § 241, and on two counts of perjury. 18 U.S.C. § 1623. The indictment and conviction arose out of the burglary of Dr. Fielding's office by members of the "Special Investigations" unit within the White House, over which Ehrlichman exercised general supervision, and out of statements made by Ehrlichman to the grand jury and the FBI, in the aftermath of the break-in. The conviction was appealed to the United States Court of Appeals for the District of Columbia, where argument was heard by a panel of Judges Leventhal, Wilkey and Merhige, the latter sitting by designation from the Eastern District of Virginia. The opinion of the court by Judge Wilkey affirms the conviction on all counts.

With regard to the conviction under 18 U.S.C. § 241 of conspiracy to violate the civil rights of Dr. Fielding, Ehrlichman raises two substantive challenges. He argues: First, that the search was legal because undertaken pursuant to a delegable Presidential power to authorize such a search in the field of foreign affairs, and; Second, that even if the search was illegal under the Fourth Amendment, Ehrlichman acted with a good faith belief in its legality, and therefore lacked the specific intent to interfere with Dr. Fielding's constitutional rights which is required for a conviction under section 241.

Dealing with the two arguments together, the court first concludes that the specific intent needed for a conviction under section 241 does not require recognition by the defendant of the unlawfulness of his acts, but only an intent to commit actions which in fact deprive a citizen of constitutional rights which are firmly established and plainly applicable. (Op. at ___-___ of 178 U.S.App.D.C., at 919-923 of 546 F.2d). The court upholds the trial judge's ruling that the intrusion infringed Dr. Fielding's firmly established Fourth Amendment right, because the legal theory advanced to justify the warrantless search is clearly inapplicable. Defendant's claim of a national security exemption to the Fourth Amendment warrant requirement is negated by the lack of any assertion of actual authorization by either the President or the Attorney General. (Op. at ___-___ of 178 U.S.App.D.C., at 923-927 of ___ F.2d). The court's opinion does not reach the alternative ground of the trial judge's ruling, that the national security exemption can never be used to justify a warrantless physical intrusion. The court finds proper the trial judge's instructions as to the other elements of the offense. (Op. at ___-___ of 178 U.S.App.D.C., at 927-928 of 546 F.2d).

Ehrlichman does not challenge his conviction on the two perjury counts on grounds of the facts and law pertaining to them, but does raise several objections applicable to all three counts, relating to the fairness of the trial and to certain procedural rulings by the trial judge. The court holds that the jury selection process was adequately safeguarded against the taint of pretrial publicity. (Op. at ___ of 178 U.S.App.D.C., at 916-917 of 546 F.2d). It holds further that the denial of Ehrlichman's motion for severance of his trial from those of Barker, Martinez, and Liddy was not an abuse of discretion, because no irreconcilable inconsistency of defenses has been shown. (Op. at ___-___ of 178 U.S.App.D.C., at 928-930 of 546 F.2d). Finally, the court rules that Ehrlichman was not denied discovery rights under Rule 16 of the Federal Rules of Criminal Procedure and the Sixth Amendment, but rather was given ample opportunity to examine and produce allegedly exculpatory White House documents, and to have the benefit of information available only from the President through interrogatories drafted by the trial court. (Op. at ___-___ of 178 U.S.App.D.C., 930-933 of 546 F.2d).

The conviction on all counts is accordingly AFFIRMED.

Judge Leventhal files a concurring statement, joined by Judge Merhige, taking issue with the claim, in the amicus memorandum of the Attorney General, that a warrantless physical intrusion may be justified by the authorization of the President or Attorney General even in the absence of exigent circumstances.

WILKEY, Circuit Judge:

On 7 March 1974 the appellant, John D. Ehrlichman, was indicted and charged with conspiracy in violation of the civil rights of Dr. Louis J. Fielding (Count I), making a false statement to agents of the Federal Bureau of Investigation (Count II), and three counts of perjury (Counts III-V). Also indicted, on the conspiracy charge alone, were G. Gordon Liddy, Bernard Barker and Eugenio Martinez. The trial commenced on 26 June 1974; on 12 July the jury returned a verdict of guilty as to Counts I-IV and not guilty as to Count V. Subsequently, the trial court entered a judgment of acquittal with respect to Count II. This appeal, therefore, is addressed to Ehrlichman's conviction on Counts I, III, and IV, conspiracy and perjury.

I. FACTUAL BACKGROUND AND ISSUES

The publication of the "Pentagon Papers" in the summer of 1971 spurred the President to form a "Special Investigations" or "Room 16" unit within the White House, whose purpose was to investigate the theft of the Pentagon Papers and prevent other such security leaks. Defendant Ehrlichman, who was the Assistant to the President for Domestic Affairs, exercised general supervision over the unit; Egil Krogh and David Young were charged with its operation. At the time, Krogh was an assistant to Ehrlichman; Young worked with the National Security Council. They sought, and received, Ehrlichman's approval to add G. Gordon Liddy, a former F.B.I. agent, and E. Howard Hunt, a former C.I.A. agent, to the unit.

Appellant's brief describes the activity of the unit, insofar as pertinent, as follows (Br. 6-8): The unit's principal enterprise seemed to be the acquisition of all files and source material on Daniel Ellsberg. There was a generalized concern over his motives for releasing classified materials (the Pentagon Papers). Young and Krogh instructed the CIA to do a psychological profile on Ellsberg. Since Dr. Fielding had refused an interview by the FBI on the ground of doctor/patient confidentiality, Hunt suggested examining Dr. Fielding's file on Ellsberg, and further suggested a "black bag job" (surreptitious entry) while noting that the FBI no longer engaged in such activities. When Young reviewed the psychological assessment on Ellsberg prepared by the CIA, he determined that it was superficial, and recommended that a "covert operation be undertaken to examine all the medical files held by Ellsberg's psychoanalyst." The exhibit reflects Ehrlichman's approval of the recommendation with his addition: "Provided that it is not traceable back to the White House."

The members of the unit were clear that the "covert operation" in question would be a surreptitious entry into Dr. Fielding's office. Ehrlichman's primary defense at trial, however, was that he was not apprised of, and thus did not authorize, such an entry. He testified that he thought he had approved only a conventional private investigation, involving no surreptitious search of Dr. Fielding's office. Considerable evidence was introduced on both sides of the question. The jury's guilty verdict on the conspiracy Count I reflected a finding that Ehrlichman had in fact authorized the search.

Krogh and Young insisted that no one employed by the White House was to effect the actual entry into Fielding's office. Hunt traveled to Miami in mid-August 1971 to enlist the assistance of Bernard Barker, who had worked under Hunt during the Bay of Pigs operation. Hunt was widely known and respected in Miami's Cuban-American community as a government agent who had been a leader in the fight to liberate Cuba. He did not identify the object of the search, but told Barker only that the operation involved a traitor who had been passing information to the Soviet Embassy. On the basis of this information Barker recruited two men, Eugenio Martinez and Felipe de Diego, for the operation.

Hunt and Liddy met Barker, Martinez, and de Diego in Los Angeles on 2 September 1971. The Miamians were informed their mission was to enter Dr. Fielding's office, that Dr. Fielding was not himself the subject of the investigation, but that they were to photograph the file of one of his patients (they were not told Ellsberg's name until minutes before the break-in) and return the file to its place. On 3 September Barker and de Diego, dressed as deliverymen, delivered a valise containing photographic equipment to Dr. Fielding's office, enabling them at the same time to unlock the door to facilitate subsequent entry. Later that evening they and Martinez, contrary to expectations, found both the building and Dr. Fielding's office locked. The Miamians forced their way into the building, broke the lock on the office door, and used a crowbar on Dr. Fielding's file cabinets. As instructed if this became necessary, they spilled pills and materials about the office to make it appear that the break-in was the work of a drug addict. Throughout the operation surgical gloves were used to avoid fingerprint detection. In spite of all efforts, Ellsberg's records eluded them.

After relating the details of the entry and their lack of success to Hunt, Barker, Martinez, and de Diego returned to Miami. Hunt and Liddy returned to Washington, where they reported the failure of the operation to Krogh and Young. Krogh relayed that information to Ehrlichman.

White House involvement in the break-in remained unknown for almost two years. When the facts about the operation began to surface, however, on 14 March 1973 Ehrlichman was called before the grand jury to testify about his knowledge of the affair. He stated that he had not been aware prior to the break-in that the Room 16 unit was looking for information with which to compose a psychological profile of Ellsberg, and had had no advance knowledge that an effort was to be made to get such information from Dr. Fielding. One year later he was indicted, subsequently tried and convicted, for his role in authorizing the break-in and for his efforts to conceal his involvement by lying to the grand jury.

Ehrlichman raises on appeal two substantive challenges to his conviction under 18 U.S.C. § 241 of conspiracy to violate the Fourth Amendment rights of Dr. Fielding. The first is that the break-in, although conducted without a judicial warrant, did not violate the Fourth Amendment, because it was undertaken pursuant to the President's delegable constitutional prerogative in the field of foreign affairs to authorize such a search. The second argument is that even if the search was unjustified in either law or fact and thus illegal, the Special Prosecutor failed to meet his burden under section 241 of proving Ehrlichman acted with a "specific intent" to interfere with Dr. Fielding's constitutional rights. As we interpret the case law surrounding section 241, the first issue — that of the applicability under these circumstances of the "foreign affairs" exemption to the warrant requirement — is bound up in the second. They will be discussed together in Part II below.

Ehrlichman does not challenge his conviction of two counts of perjury on substantive grounds relating particularly to those counts or to the law of perjury. He does, however, attack his conviction as a whole — both for conspiracy and for perjury — on a number of grounds relating to the fairness of the trial and certain of the District Court's procedural rulings. His principal argument is that he was denied a fair trial, in the light of prejudicial pre-trial publicity, when the court failed to dismiss the indictment, continue or change the venue of the trial, or conduct a voir dire adequate to eliminate possibly prejudiced jurors. Our close examination of the procedures followed by the trial judge has satisfied us that he properly made the determinations required of him under the controlling decisions of this court.

Subsidiary arguments advanced by Ehrlichman against the conduct of the trial are levelled at the District Court's decision not to sever Ehrlichman's prosecution from that of his co-defendants, the court's refusal to order certain discovery Ehrlichman claimed was important to his defense, and the court's failure to require then-President Nixon to testify or to respond to detailed interrogatories propounded by Ehrlichman. These issues we take up in Part III.

II. GOOD FAITH AS A DEFENSE TO "SPECIFIC INTENT" UNDER 18 U.S.C. § 241

The most substantial argument advanced by defendant Ehrlichman on appeal from his conviction under 18 U.S.C. § 241 is that the District Court's mistaken legal view of the statute's "specific intent" requirement led the court to commit reversible error, both in ruling on the admissibility of certain evidence sought to be introduced by him and in instructing the jury on the basic elements of the offense. Not every conspiracy affecting a citizen's constitutional rights falls within the prohibition of section 241. It is settled law that "the offender must act with a specific intent to interfere with the federal rights in question . . .." Ehrlichman contends that he acted without the requisite "specific intent" to invade Dr. Fielding's Fourth Amendment rights, since he agreed to a search of the doctor's office in the good faith belief that it would involve no violation of the law, constitutional or otherwise.

Prior to trial Ehrlichman and his co-defendants presented this theory of the case to the District Court in connection with motions for discovery of certain national security information. They took the position that the information would provide factual support for their asserted belief in the legality of the Fielding operation. The District Court rejected the defendants' theory, and their motions, in the following language:

Defendants contend that, even if the break-in was illegal, they lacked the specific intent necessary to violate section 241 because they reasonably believed that they had been authorized to enter and search Dr. Fielding's office. As explained above, however, such authorization was not only factually absent but also legally insufficient, and it is well established that a mistake of law is no defense in a conspiracy case to the knowing performance of acts which, like the unauthorized entry and search at issue here, are malum in se. [Cites] As the Supreme Court said in Screws v. United States, 325 U.S. 91, 106, 65 S.Ct. 1031, 1037, 89 L.Ed. 1495 (1945), "[t]he fact that the defendants may not have been thinking in constitutional terms is not material [to a charge under § 242, a related specific intent statute,] where their aim was not to enforce local law but to deprive a citizen of a right and that right was protected by the Constitution." Here, defendants are alleged to have intended to search Dr. Fielding's office without a warrant, and their mistaken belief that such conduct did not offend the Constitution would not protect them from prosecution under section 241. See also Williams v. United States, 341 U.S. 97, 101-102, 71 S.Ct. 576, 95 L.Ed. 774 (1951).

As a result of the District Court's ruling, Ehrlichman was restricted during the trial in his ability to obtain and introduce evidence of the national security circumstances surrounding the Fielding operation. At the end of the trial, the court rejected jury instructions which provided that belief in the legality of one's conduct could negate "specific intent" under section 241, and advised the jury that the requisite intent would be established under section 241 if the Prosecutor showed simply "that the object of the conspiracy and the purpose of each defendant was to carry out a warrantless entry into and search of Dr. Fielding's office without permission."

The trial judge's position, as set forth in both his pre-trial opinion and in his instructions to the jury, unquestionably states the law with regard to the vast majority of criminal conspiracies. Even though all such conspiracies are crimes of "specific intent" — in that the defendant must not only combine with others but also intend to commit unlawful acts — generally there is no requirement that the conspirator know those acts to be unlawful. A mistake as to the legality of the prohibited activity, therefore, is no defense.

The doctrine that a mistake of law will not excuse a crime normally applies in conspiracy cases even when the target offense itself has "specific intent" as an element. The reason for this is that the mental state required for most "specific intent" offenses does not involve knowledge of illegality. If the recognition of the unlawfulness of one's action is not an element of the substantive crime, neither is it a component of the offense of agreeing to commit the crime.

Significantly, however, some "specific intent" crimes can be committed only if the defendant performs the actus reus with an intention to violate the law, or without ground for believing his action is lawful. A good faith mistake as to the legality of his activity, or failure to act, is a valid defense to prosecution for such a crime. Equally important, such a mistake necessarily also constitutes a defense to a charge of conspiracy to commit this kind of "specific intent" crime.

In sum, whether the District Court properly rejected the good faith defense proffered by Ehrlichman is a question whose answer rests, in the first instance, on the mens rea required to commit the target offense under section 241. We examine the nature of that section's "specific intent" requirement in Subsection A and apply our legal findings to the facts surrounding the Fielding break-in in Subsection B, infra. Our conclusion is that under the circumstances of this case the District Court did not err in rejecting the defendant's good faith defense.

A. The "Specific Intent" Requirement of Section 241 1. Screws v. United States

The substantive counterpart to section 241 is 18 U.S.C. § 242, which provides in pertinent part:

Whoever, under color of any law, statute, ordinance, regulation, or custom, willfully subjects any inhabitant . . to the deprivation of any rights, privileges, or immunities secured or protected by the Constitution or laws of the United States, . . . shall be fined not more than $1,000 or imprisoned not more than one year, or both; and if death results shall be subject to imprisonment for any term of years or for life.

The seminal case dealing with the element of mens rea under section 242 in Screws v. United States. The defendants in Screws, law enforcement officials who had beaten a prisoner to death, were charged with denying that individual various of his due process rights under the Fourth Amendment. They countered with an attack on the constitutionality of section 242 — arguing that if it incorporated such a large body of changing and uncertain law as surrounds the concept of due process, the statute lacked the basic specificity essential to criminal statutes under our legal system.

The Court acknowledged that this "vagueness" challenge would be serious if the "customary standard" of guilt for statutory crimes were applied under section 242. The presence of the term "willfully" in the statute, however, afforded the Court, a convenient means for narrowing its potential reach — not only to fulfill the constitutional requirement of specificity but also to prevent the federal statute from becoming a "catchall" which might interfere with the traditional law enforcement role of the states. The Court noted, first, that precise construction of the word "willful" in a statute was dependent on its context. "But `when used in a criminal statute it generally means an act done with a bad purpose.'" It requires a particular intent in addition to the performance of the act required by the statute.

The Court determined that for the purposes of section 242 acting "willfully" meant acting with "a purpose to deprive a person of a specific constitutional right," "made definite by decision or other rule of law." Such a construction, in the Court's view, would cure the problem of vagueness presented by the statute:

One who does act with such specific intent is aware that what he does is precisely that which the statute forbids. He is under no necessity of guessing whether the statute applies to him . . . for he either knows or acts in reckless disregard of its prohibition of the deprivation of a defined constitutional or other federal right. . . . The Act would then not become a trap for law enforcement agencies acting in good faith. "A mind intent upon willful evasion is inconsistent with surprised innocence." United States v. Ragen, [ 314 U.S. 513, 524, 62 S.Ct. 374, 378, 86 L.Ed. 383 (1942).]

The Court observed that the indictment in United States v. Classic, an earlier case involving section 242, met the test of "specific intent" it had just laid down. That indictment charged the defendants with, inter alia, the willful alteration of ballots. Such alteration, the Court emphasized, clearly breached a right expressly guaranteed by the Constitution — viz., the right to vote. The indictment did not charge that the defendants had acted with the specific intent to deprive voters of their constitutional prerogatives. Nevertheless, the Court concluded:

Such a charge is adequate since he who alters ballots or without legal justification destroys them would be acting willfully in the sense in which [ § 242] uses the term. The fact that the defendants may not have been thinking in constitutional terms is not material where their aim was not to enforce local law but to deprive a citizen of a right and that right was protected by the Constitution. When they so act they at least act in reckless disregard of constitutional prohibitions or guarantees.

Turning to the charge against the defendants in Screws itself, the Court observed, "Likewise, it is plain that basic to the concept of due process of law in a criminal case is a trial — a trial in a court of law, not a `trial by ordeal.'" No allegation of intent to breach a constitutional right, therefore, was necessary. The Court held that the "specific intent" requirement of section 242 would be met if the jury were instructed simply that to convict they must find the defendants had beaten their prisoner to death with the particular purpose of subjecting him to a trial by ordeal.

2. The Meaning of Screws

Although some of the language in Screws can be read more broadly, its holding essentially sets forth two requirements for a finding of "specific intent" under section 242. The first is a purely legal determination. Is the constitutional right at issue clearly delineated and plainly applicable under the circumstances of the case? If the trial judge concludes that it is, then the jury must make the second, factual, determination. Did the defendant commit the act in question with the particular purpose of depriving the citizen victim of his enjoyment of the interests protected by that federal right? If both requirements are met, even if the defendant did not in fact recognize the unconstitutionality of his act, he will be adjudged as a matter of law to have acted "willfully" — i. e., "in reckless disregard of constitutional prohibitions or guarantees."

These "specific intent" requirements, grafted by the Supreme Court onto the elements of a section 242 violation, met the Court's twin concerns of vagueness and federalism in Screws. On the one hand, the requirement that the constitutional right in question be clearly established provides the specificity needed for a criminal statute to meet minimal standards of due process. On the other hand, the requirement that the defendant have a purpose to infringe federally protected interests preserves the states' traditional prerogative to prosecute and punish those who commit ordinary crime. For example, as Screws illustrates, the Constitution clearly grants protection to a citizen's interests in not being punished by governmental officials without a trial. There is no violation of section 242, however, if a sheriff and his deputies commit a murder for purely personal, nongovernmental reasons. The state can, and should, deal with such crime. Section 242 comes into play only if the object of the murder was to punish a prisoner for past illegal acts, or for some other purpose stemming from the official position of those committing the homicide.

The same principles apply to prosecutions for conspiracy under section 241. Although the language of sections 241 and 242 is somewhat different — indeed, section 241 does not contain the word "willfully" — the Supreme Court has made clear since Screws that the "specific intent" requirements of section 242 are equally applicable (or derivatively applicable) to section 241. In United States v. Guest, decided in 1966, the Court reversed the dismissal of an indictment charging the defendants with violating section 241 by, inter alia, conspiring to intimidate blacks in the free exercise of the right of interstate travel. The Court observed, first, that the rights of equal utilization of public facilities and freedom of travel had been firmly established and repeatedly recognized; therefore, the requirement of constitutional clarity presented no difficulty. Second, the Court noted with reference to the right to travel that under Screws not every criminal conspiracy which incidentally interfered with that right is prohibited by section 241. A conspiracy to rob a private person who happens to be traveling interstate, for example, would not violate section 241, because it would entail no purpose to invade federally protected interests. On remand, therefore, the Court found that the prosecution would have to show the defendants conspired to intimidate an individual because he was traveling interstate.

Most recently, in Anderson v. United States, decided in 1974, the Court reaffirmed and further elucidated the "specific intent" requirements of section 241. Since the constitutional right in question was the right to an equal vote in a federal election, the defendants convicted of casting false votes could not be assailed on the ground that the federal interests involved were not clear and firmly established. Rather, the main issue was whether an intent to invade those federal interests had been proven, in view of the fact that the primary objective of the conspiracy was to influence a local election — even though false votes had been cast for candidates for federal office as well. The Court found adequate evidence of "specific intent," concluding:

A single conspiracy may have several purposes but if one of them — whether primary or secondary — be the violation of federal law, the conspiracy is unlawful under federal law.

* * * * * *

That petitioners may have had no purpose to change the outcome of the federal election is irrelevant. The specific intent required under § 241 is not the intent to change the outcome of a federal election, but rather the intent to have false votes cast and thereby injure the right of all voters in a federal election to express their choice of a candidate and to have their expressions of choice given full value and effect, without being diluted or distorted by the casting of fraudulent ballots.

Screws and its progeny thus compel the conclusion that the specific intent required to violate section 241 is the purpose of the conspirators to commit acts which deprive a citizen of interests in fact protected by clearly defined constitutional rights. If that purpose was present, there is no "good faith" defense, such as Ehrlichman proffers, because of lack of awareness of the conspirators at the time they commit the proscribed acts that they are violating constitutional rights. There is no requirement under section 241 that a defendant recognize the unlawfulness of his acts.

It should be added here that there is also no support for Ehrlichman's position in any of the recognized common law exceptions to the mistake of law doctrine, which are developed more fully in our opinions in the companion decision on Barker and Martinez. Ehrlichman's reliance on Pierson v. Ray is misplaced. In Pierson the Supreme Court held that a police officer sued under 42 U.S.C. § 1983 for an unlawful arrest could raise as a defense his reliance on a statute which he reasonably believed to be valid but which was later held unconstitutional. Assuming arguendo that an analogous defense should be made available in a criminal case, it still cannot avail the defendant here. As is detailed in Subpart II.B., infra, the violation of the Fourth Amendment in this case was clear. Ehrlichman cannot and does not argue that he should be allowed a defense based upon his reasonable reliance on an apparently valid statute or judicial decision, nor does his invocation of the claimed foreign affairs exception to the warrant requirement avail him, for even the claim of a foreign affairs exception has consistently been conditioned on specific approval by the President or the Attorney General. Ehrlichman was himself a high government official. He does not contend that specific judicial or Presidential approval was obtained for the Fielding break-in. He simply asserts that it was his belief that the break-in was lawful notwithstanding the absence of any such specific approval. Such a mistake of law can be no defense. Neither Pierson nor any other authority countenances an exception to the mistake of law doctrine in such a situation.

It still remains to determine whether the instructions the court gave the jury met the two-pronged test of "specific intent" laid down in Screws. We turn now to this inquiry.

B. Conformity of Jury Instructions with "Specific Intent" Requirements 1. The Requirement that the Protected Right Be Firmly Established and Plainly Applicable

Defendant Ehrlichman is charged with violating Dr. Fielding's Fourth Amendment rights by conspiring in the breaking and entering of his office. The Fourth Amendment provides that "the right of the people to be secure in their persons, houses, papers and effects, against unreasonable searches and seizures, shall not be violated; and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized." Although the best means of protecting this right against incursions by "overzealous executive officers" has been subject to some debate, the core meaning of the Fourth Amendment was clear well before defendants conspired to search Dr. Fielding's files:

[T]ranslation of the abstract prohibition against "unreasonable searches and seizures" into workable guidelines for the decision of particular cases is a difficult task . . . . Nevertheless, one governing principle, justified by history and by current experience, has consistently been followed: except in certain carefully defined classes of cases, a search of private property without proper consent is "unreasonable" unless it has been authorized by a valid search warrant. . . .

United States v. United States District Court (Keith) capsulized that historic approach in noting that "physical entry of the home is the chief evil against which the wording of the Fourth Amendment is directed." "The very heart of the Fourth Amendment directive" is that "where practical, a government search and seizure should represent both the efforts of the officer to gather evidence of wrongful acts and the judgment of the magistrate that the collected evidence is sufficient to justify invasion of a citizen's private premises or conversation." The framers formulated that directive against the background of Entick v. Carrington, a case found by the Supreme Court in Boyd v. United States to be "sufficiently explanatory of what was meant by unreasonable searches and seizures." Entick overturned an executive warrant to search the studies of political dissidents.

As a general proposition, few would question the clarity of the Fourth Amendment right of every citizen to be free from governmental searches and seizures unless sanctioned by judicial warrant based on probable cause. For the purposes of section 241, however, that right may not be clear in an individual case if the circumstances are such that an exception to the warrant requirement may be invoked. Just how clear was Dr. Fielding's right to be free from the search directed by defendant Ehrlichman is the question we examine at this point.

In pre-trial proceedings before the District Court Ehrlichman claimed that the break-in was not in violation of Dr. Fielding's Fourth Amendment rights and developed a contention along the following lines: The entry was undertaken pursuant to an authorized "foreign affairs" or "national security" operation. Since 1940 the "foreign affairs" exception to the prohibition against wiretapping has been espoused by the Executive Branch as a necessary concomitant to the President's constitutional power over the exercise of this country's foreign affairs, and warrantless electronic surveillance has been upheld by lower federal courts on a number of occasions. No court has ruled that the President does not have this prerogative in a case involving foreign agents or collaborators with a foreign power. The Supreme Court, in a number of decisions requiring officials to obtain a warrant before engaging in electronic surveillance, has been careful to note that its rulings do not reach such cases.

Hoping to fall within this as yet not fully defined exception, Ehrlichman urges that in September 1971 "in a matter affecting national security and foreign intelligence gathering" the absence of a judicially approved warrant did not render unlawful "a search and seizure authorized by a presidential delegate pursuant to a broad Presidential mandate of power given to that delegate."

Ehrlichman further argues that no specific authorization by the President or the Attorney General was required:

Implicitly, an instruction to accomplish an end carries with it the duty of performing all lawful acts necessary to accomplish that end. In the instant case, the President delegated the power, to sworn officials of the Executive Branch, including Appellant Ehrlichman, to prevent and halt leaks of vital security information. To contend that the President must specifically chart out the methods of employing the power, each and every time he delegates power is absurd.

The District Court ruled as a matter of law that the national security exemption did not excuse the failure to obtain a judicial warrant for a physical search of Dr. Fielding's office either because there is no exemption for physical searches or because the exemption can only be invoked by the President or the Attorney General in a particular case. This holding, which governed pre-trial discovery instructions to the jury, blocked any evidentiary inquiry into the factual basis for Ehrlichman's alleged belief that the Fielding "covert operation" could yield significant foreign intelligence information. For purposes of this appeal, we accept as possible of proof that probable cause existed for the operation, so that if application for a warrant had been made it would have been granted.

The District Court's ruling was based on two premises. The first is that the "national security" exemption has been "carefully limited to the issue of wiretapping, a relatively nonintrusive search." The circuit court decisions setting forth such an exemption for "the special problem of national security wiretaps" do not go so far as to dispense with the need for a warrant as a requirement for "physical entry of the home . . . the chief evil against which the wording of the Fourth Amendment is directed." We need not in this opinion decide this matter one way or the other, and no inference should be drawn from our failure to discuss it. It suffices to dispose of the case at bar that we find that the District Court was unquestionably correct in its second ground for rejecting Ehrlichman's claim, in its ruling that in any event the "national security" exemption can only be invoked if there has been a specific authorization by the President, or by the Attorney General as his chief legal advisor, for the particular case.

Neither Ehrlichman nor any of his codefendants have alleged that the Attorney General gave his approval to the Fielding operation; and none has attempted to refute former President Nixon's assertion that he had no prior knowledge of the break-in and, therefore, could not and did not authorize the search. Ehrlichman soars into a novel claim of authority. No court has ever in any way indicated, nor has any Presidential administration or Attorney General claimed, that any executive officer acting under an inexplicit Presidential mandate may authorize warrantless searches of foreign agents or collaborators, much less the warrantless search of the offices of an American citizen not himself suspected of collaboration.

The defendant totally misapprehends the critical role played by the President and the Attorney General, when the "national security" exception is invoked. It is argued that this exception gives government officials the power surreptitiously to intrude on the privacy of citizens without the necessity of first justifying their action before an independent and detached member of the judiciary. Unless carefully circumscribed, such a power is easily subject to abuse. The danger of leaving delicate decisions of propriety and probable cause to those actually assigned to ferret out "national security" information is patent, and is indeed illustrated by the intrusion undertaken in this case, without any more specific Presidential direction than that ascribed to Henry II vexed with Becket. As a constitutional matter, if Presidential approval is to replace judicial approval for foreign intelligence gathering, the personal authorization of the President — or his alter ego for these matters, the Attorney General — is necessary to fix accountability and centralize responsibility for insuring the least intrusive surveillance necessary and preventing zealous officials from misusing the President's prerogative.

Mr. Justice White, concurring separately in Katz v. United States, noted the possibility of recognizing a "national security" exception to the warrant requirement for electronic surveillance, but only if "the President of the United States or his chief legal officer, the Attorney General, has considered the requirements of national security and authorized electronic surveillance as reasonable." As of this writing, that is the only statement by any Supreme Court Justice declaring a national security exemption. Mr. Justice Stewart, concurring in Giordano v. United States, noted that "[w]hile two members of the Court have indicated disagreement with that view, the issue remains open." Moreover, the Government in its brief before the Supreme Court in United States v. United States District Court (Keith), stated flatly, "We urge the Court to adopt the principle that Mr. Justice White suggested in his concurring opinion in Katz." The Government's argument was based in substantial part on the protection and consistency that would derive from a procedure centered on the Attorney General himself. The Court in Keith noted that ". . . the President — through the Attorney General — may find it necessary to employ electronic surveillance to obtain intelligence information on the plans of those who plot unlawful acts against the Government." Yet even this expression was in the context of an opinion that held that Constitution required a judicial warrant as a condition for conducting domestic security surveillance, and disclaimed expression of any ruling on the requirement applicable in the case of activities of foreign powers or their agents.

As a historical matter, Presidential memoranda from 1940 to 1965 setting forth Executive policies regarding national security electronic surveillance have stressed the requirement of personal approval by the President or the Attorney General, even though at the time the Supreme Court had held that the Constitution did not require a warrant for such surveillance. No court, Justice of the Supreme Court, or Presidential administration has ever suggested a power which could be generally delegated, for example, even to regular intelligence agencies, like the FBI and CIA, let alone to the extrastatutory group involved in the instant case. Even though the employees and administrators of the regular agencies might have the background, training, and departmental discipline to make responsible, expert decisions, the risk of their myopic abuse of such a powerful prerogative is simply too great to permit its delegation. That risk is substantially magnified when the decision-making group, as here, is an amorphous, ad hoc unit with no tradition of public service and no clear lines of responsibility.

Skepticism of power to delegate "authority at will" to make crucial decisions in the Fourth Amendment area led the Supreme Court to hold invalid a delegation within the Department of Justice of the statutory power to authorize even the application for a wiretap warrant to be issued by a magistrate once a probable cause determination is made. The Court insisted that "[t]he mature judgment of a particular, responsible Department of Justice official [be] interposed as a critical precondition to any judicial order." A fortiori, when what is involved is a claim that an exception permits a Chief Executive determination to replace the neutral magistrate altogether, that determination cannot be delegated. Talismanic invocation of "national security" is not a basis for delegation, it is at most a basis for the claim that there may be a "Chief Executive warrant."

Although Ehrlichman's counsel speak broadly of Presidential authorization, all that they show is that the President authorized the formation of a unit within the White House to stop security leaks and investigate the Ellsberg matter. At no point did the President even mention the possibility of surreptitious wiretaps or other "national security" searches — let alone give any specific authorization for such activity. The law is plain that the simple fact that the President asks a subordinate official to investigate and report on a problem involving national security does not give the official plenary power to exercise all prerogatives the President might have in that area.

Ehrlichman can hardly mean that the President intended to give him all the power that he, the President, had. Obviously, the most that could be argued was the authority to perform "lawful acts necessary to accomplish that end." Whatever the rule for the President, the delegate may not claim, as lawful acts, those which could not be lawfully delegated to his discretion.

As a constitutional matter, if and to the extent that Presidential approval may replace judicial approval for foreign intelligence gathering, the personal authorization of the President — or of his Cabinet alter ego for these matters, the Attorney General — is necessary to fix accountability and centralize responsibility for insuring the least intrusive surveillance necessary and preventing zealous officials from misusing the Presidential prerogative.

Under the circumstances of this case, the law is clear that Dr. Fielding's Fourth Amendment rights were breached when the defendants broke into and searched his office without the requisite judicial authorization. For the purposes of the element of "specific intent" in section 241, it remains only to determine whether the defendants acted with the necessary purpose of trenching upon constitutionally protected interests.

2. The Requirements of a Purpose to Invade Constitutionally Protected Interests.

As we observed above in connection with our discussion of Screws and its progeny, "specific intent" under section 241 does not require an actual awareness on the part of the conspirators that they are violating constitutional rights. It is enough that they engage in activity which interferes with rights which as a matter of law are clearly and specifically protected by the Constitution. As we have already pointed out, in this case the law clearly establishes a violation of Dr. Fielding's Fourth Amendment right to be secure against the warrantless entry and search, the exceptions for entry without a judicial warrant being plainly inapplicable.

It is not a violation of section 241 for individuals who happen to be government agents to burglarize a doctor's office for purely personal gain. It is a civil rights conspiracy in violation of that section, however, if they enter his office in their capacity as government agents without proper authorization to secure information for an ostensible government purpose. The concern of Congress in enacting section 241 was to extend the federal police power to those who intentionally interfere with federally protected interests — e. g., officials whose specific purpose is to accomplish the governmental objectives of punishment or obtaining confessions or searching private premises, individuals who act with the particular intent of preventing other citizens' equal use of the polls or the interstate highways. The objective must be governmental even though section 241, unlike section 242, does not require that conspirators act under color of law. The states can deal with those who kill or mug or burglarize out of passion or greed for purely personal reasons.

The District Court instructed the jury as follows:

To establish a violation of count one of the indictment, the conspiracy count, the prosecutor must prove beyond a reasonable doubt, first, that a conspiracy existed between one or more defendants or unindicted co-conspirators named in the indictment.

Second, that the purpose of the conspiracy was to carry out a warrantless entry and search of Dr. Fielding's office without his permission.

Third, that the conspirators were governmental employees or agents who intended to enter and to search Dr. Fielding's office without a warrant or permission for governmental rather than purely personal reasons.

Fourth, that Dr. Fielding himself was at the time an American citizen.

These instructions state the law exactly as we have outlined it, and Ehrlichman does not contest that if those instructions were legally correct there was substantial evidence to sustain his conviction under section 241.

Thus, we conclude that Ehrlichman's conviction of conspiracy as set forth in Count I of the indictment was in full compliance with the mens rea requirements of section 241. We turn now to a brief discussion of the defendant's remaining contentions on appeal.

III. SUBSIDIARY ISSUES

A. Severance

The District Court's refusal to grant Ehrlichman's request for a severance can constitute grounds for reversal only if the defendant sustains the burden of showing a clear abuse of discretion by the court. Ehrlichman relies primarily on an alleged inconsistency between his defense and that of his co-defendants, but it appears axiomatic that "the mere presence of hostility among defendants or the desire of one to exculpate himself by inculpating another [are] insufficient grounds to require separate trials." To obtain a severance on the ground of conflicting defenses, "[a]t the very least, it must be demonstrated that a conflict is so prejudicial that differences are irreconcilable, and that the jury will unjustifiably infer that this conflict alone demonstrates that both are guilty.'"

No such irreconcilable inconsistency of defenses is shown here. Ehrlichman asserts that Liddy, Barker, and Martinez effectively contended that he had approved the break-in; and as their "superior" he, not they, should be held responsible for the break-in. At no point, however, did Liddy assert that he had acted under Ehrlichman's orders, nor did he argue that Ehrlichman had approved the Fielding entry and search. Rather, his defense was based upon the belief that a warrant had been obtained. Liddy's references to Ehrlichman's position as "nominal supervisor" of the "Room 16" unit, his place in the White House chain of command, and his familiarity with the President's instructions to the unit do not — contrary to Ehrlichman's contention — constitute a charge that Ehrlichman specifically approved a surreptitious entry. There would have been no logical inconsistency in the jury's acceptance of the defenses presented by both defendants.

Even less tenable is the argument that the defense of Barker and Martinez trenched upon that of Ehrlichman. They made no reference whatever to Ehrlichman in presenting their claim of good faith belief in apparent authority. Their defense was based on the circumstances of their relationship with Hunt. It was totally irrelevant to Barker's and Martinez's position whether Ehrlichman had or had not approved the break-in, for they made no claim of such specific knowledge.

Ehrlichman also relies on the " De Luna doctrine" to support his request for severance. He claims that the District Court's refusal to sever, which precluded any comment by him on Liddy's failure to take the stand, unduly prejudiced his defense. It would appear clear, however, that severance is not required simply because one defendant may wish to comment on another's refusal to testify. In De Luna, two defendants, tried jointly on narcotics charges, each claimed the other was solely responsible. In the presence of mutually exclusive and irreconcilable defenses, the importance to one defendant of the ability to comment on the silence of his co-defendant was overwhelming. No such inconsistent defenses are present here, and Liddy was the only one of seven of Ehrlichman's alleged co-conspirators who failed to take the stand. Under these circumstances, we do not find that the District Court abused its discretion in refusing to sever Ehrlichman's trial from that of his co-defendants.

B. Ehrlichman's Discovery Rights

Ehrlichman claims he was improperly denied in his rights under Rule 16 of the Federal Rules of Criminal Procedure to the production of all evidence material to the preparation of his defense and, under Brady v. Maryland, to all evidence "favorable to an accused." The Special Prosecutor asserts that he voluntarily produced all documents in his possession which were even remotely relevant to the issues to be tried. Further, he contacted all governmental departments, including the White House, which might be expected to have material possibly exculpatory of Ehrlichman or his co-defendants. These departments reported the results of their searches in affidavits. On appeal Ehrlichman apparently does not question the accuracy of these affidavits or their fulfillment of the prosecution's obligation to disclose relevant information to the defense, with the exception of the affidavit filed by J. Fred Buzhardt on behalf of the White House. As to the Buzhardt affidavit, however, Ehrlichman failed to present any evidence before the District Court to support his argument here that Buzhardt's review generally was inadequate or his representations inaccurate. Nor has he presented any such evidence to us. Ehrlichman's broad challenge to the validity of Buzhardt's inspection of White House files for materials relevant to Ehrlichman's defense must fail.

We are left with the arguments made by Ehrlichman with respect to specific materials held by the White House which he desired produced. The first of these were Ehrlichman's notes recording private Presidential conversations and meetings. As part of his overall review referred to above, Buzhardt examined those notes, found none bearing on the guilt or innocence of Ehrlichman or his co-defendants, but turned over Xerox copies of those that seemed conceivably relevant. Moreover, Ehrlichman was given personal access to all the notes. In response to the trial judge's repeated request that Ehrlichman specify which notes of individual conversations he considered had been improperly withheld, Ehrlichman on 21 June 1974 filed a motion for the issuance of a subpoena duces tecum for the notes of ten different conversations. An accompanying memorandum detailed Ehrlichman's reasons for considering those particular notes material to his defense. In response to that motion the White House turned over the requested notes to the trial judge for in camera inspection. Also, on 24 June the Special Prosecutor filed a lengthy memorandum arguing the irrelevancy of each of the conversations sought to the issues at trial. With the actual notes before him, Judge Gesell found the Special Prosecutor's position persuasive and quashed the subpoena. We have reviewed these notes as well and find ourselves in complete accord with the trial judge's determination. With the exception of the "Leaks" file, discussed below, Ehrlichman identifies on appeal no other specific documents or notes which were wrongfully denied him.

Nevertheless, Ehrlichman argues, first, that the District Court should have ordered the White House to submit to it all his notes of Presidential conversations and, apparently, all other White House material Ehrlichman requested for in camera inspection to determine their relevance. Even were this a case not involving "presumptively privileged Presidential files, Ehrlichman's failure to argue with specificity the materiality and reasonableness of his discovery request would render his position untenable. In the face of the requirement for a "demonstrated specific need" for the evidence or a showing "that the Presidential material was `essential to the justice of the [pending criminal] case,'" we must reject his position.

Second, Ehrlichman contends he was deprived of his Sixth Amendment right to counsel when the President permitted Ehrlichman, but not his attorney, to examine his notes. The fact that Ehrlichman was given access to these files — which recorded Presidential conversations apparently unrelated to the Fielding break-in — could not vest a right of access in his attorney, who was not privy to the conversations. The order did not prevent Ehrlichman from leaving the room where the files were located at any time to inform his attorney in detail of the materials he had located. Ehrlichman does not contend that his attorney would have been prevented from framing subpoenas duces tecum for relevant material so located. In sum, the District Court committed no error with respect to its handling of the discovery of Ehrlichman's notes.

The only evidence Ehrlichman specifically alleges to be exculpatory and wrongfully withheld is the so-called "Leaks" file. On 26 March 1973, a briefcase filled with files on the "Pentagon Papers" investigation, which had been in the possession of David Young, was delivered to Ehrlichman's office. Before that delivery, Young photocopied those documents which implicated Ehrlichman in the Fielding break-in. Young testified at trial that Ehrlichman later told him he had removed certain of the documents which were most incriminating before returning the files to Young, and that Young verified this fact when reviewing the files. Ehrlichman testified that he had not removed those memoranda. Eventually, the documents would up in a file marked "Leaks," in a box marked "Ehrlichman," in the White House.

Ehrlichman contended at trial that production of the file was necessary to show he was involved in legitimate efforts to tighten security and prevent leaks within the government. The President's attorney, James St. Clair, indicated in a hearing on the matter that the file contained numerous classified documents not relating to Dr. Fielding or David Ellsberg. He indicated, however, that he thought the President would permit disclosure of specific documents from the file if such a request were made. Ehrlichman never submitted such a request nor showed why production of the entire file was necessary to his defense.

On appeal, however, for the first time Ehrlichman argues that production of the file folder was important to show that the designation "Leaks" on the folder was not in his handwriting and the file had been created by someone else. Not only is this theory produced at much too late a date, but it is extremely doubtful that such evidence could have influenced the jury's verdict. We find therefore, that Ehrlichman has not show sufficient actual prejudice to his case to justify reversal of his conviction for the District Court's refusal to order the production of the "Leaks" file.

C. The Sufficiency of the District Court's Interrogatories to the President

Ehrlichman's final argument is that the District Court erred in failing either to require then-President Nixon to appear as a witness at trial or answer detailed interrogatories propounded by the defendant. First, it would appear that if a subpoena duces tecum on a President may only be enforced where there is a "demonstrated specific need" for the testimony or the testimony is "essential to the justice of the [pending criminal] case," certainly a more burdensome subpoena ad testificandum would have to meet at least equal standards. Neither Ehrlichman nor any of his co-defendants, however, claims that the President specifically authorized the break-in. The Special Prosecutor disclaimed any evidence indicating Presidential authorization and the President himself denied even having had prior knowledge of the Fielding operation. In the absence of claim of direct Presidential involvement, and in view of the substitute procedure available to the defendant of propounding interrogatories, we find unpersuasive Ehrlichman's argument that President Nixon should have been compelled to appear as a witness.

Second, as to the detailed interrogatories submitted by Ehrlichman, we find, as did the District Court, that many of the questions were repetitive or irrelevant to the issues properly before the court. The court drafted concise questions addressed to the central issues of the Ehrlichman submission and the President answered these. Ehrlichman contends, however, that the court's interrogatories were inadequate to explore the issue whether concealment of the activities of the "Room 16" unit was undertaken pursuant to Presidential order, to protect highly classified information, or whether such concealment was intended instead to mask wrongdoing. Our comparison of the interrogatories submitted by the defendant and those formulated by the court on this issue lead us to reject this contention. It appears highly unlikely that the President's answers would have differed in any significant respect had Ehrlichman's submission been adopted. Moreover, the President's response to the court's interrogatories revealed that he would have had little useful testimony to give on the question of concealment — even assuming the relevance of that question to the issues at trial — if he had been called to testify in person.

Conclusion

For the foregoing reasons, the District Court judgment is

Affirmed.
