Federal Bureau of Investigation

The Federal Bureau of Investigation (FBI) was both a principal investigative body in the Watergate affair and an institution whose methods and limits became part of the story. Its agents followed evidence from the break-in toward campaign connections and a broader political operation, but the investigation also encountered controlled interviews, information that stalled after referral to the Justice Department, and scrutiny of the Bureau’s surveillance practices. The record presented here shows an institution whose work generated consequential leads while its access, independence, and handling of sensitive information remained contested.

Role and Early Watergate Investigation

The connection between the break-in and the Nixon campaign became concrete the morning after the arrests. A report on the Associated Press wire identified James McCord as the security coordinator for the Committee for the Re-election of the President. The national staff of The Washington Post rarely covered police matters, but Barry Sussman asked Carl Bernstein and Bob Woodward to return to the office on Sunday, June 18, and pursue the story. McCord’s campaign position showed why the burglars’ identities required further checking: the case could not safely be treated as an isolated crime.

The FBI’s investigation of campaign personnel took place at the committee’s headquarters rather than in employees’ homes. Interviews were held in the presence of a committee lawyer or Robert Mardian, the committee’s political coordinator and a former Justice Department official. People in positions likely to know about the bugging, including secretaries, appeared not to have been interviewed. Some employees said they had been instructed not to volunteer information to agents unless asked a specific question they could not evade, particularly about committee finances. The FBI was therefore gathering evidence in an environment where access to witnesses and the conditions of their interviews were closely managed.

The committee itself was difficult for outsiders to penetrate. Since June 17, visitors had encountered a uniformed guard, been cleared by press or security staff, escorted to appointments, and led back out. A roster listing more than one hundred campaign officials was treated as classified. The secrecy around the organization contrasted with the FBI’s need to establish who knew what about the operation, and it helps explain why ordinary personnel and financial details became important investigative and reporting leads.

Leads, Sources, and the Wider Operation

The Bureau’s investigative trail extended beyond the break-in. A Justice Department lawyer told Bernstein that investigators had identified Donald Segretti through telephone records associated with E. Howard Hunt. The Bureau had made random checks on a large portion of Hunt’s calls—more than seven hundred altogether—and one call reached Segretti. The lawyer emphasized that the political dirty tricks were probably not illegal and that Justice was concentrating on the Watergate bugging. He also voiced concern that the Bureau was behaving unusually and that there was interest in the case at a high level, without identifying where that interest came from.

The connection was suggestive, but its limits mattered. Segretti told Larry Young that Hunt had given him instructions, while Young did not know what specific events those instructions concerned; they were not connected to the bugging itself. The telephone relationship opened a route toward political espionage and sabotage, but it did not by itself establish the purpose of every call or prove that the dirty tricks were part of the break-in. The distinction between discovering a network and demonstrating what each person authorized or did remained central to the investigation.

A Justice Department official who had originally told Bernstein that Segretti was part of the investigation later refused to answer a question on the grounds that it belonged to the investigation. Separately, a source confirmed that the Bureau had encountered information about political espionage and sabotage but had done nothing with it: the information went through channels to Justice and never came back. This account points to a consequential institutional boundary. The FBI could encounter information beyond the immediate burglary, yet referral did not guarantee that the wider material would be pursued or returned to investigators.

The Bureau’s work also became difficult to separate from the reporters’ efforts to verify their own stories. After The Washington Post published stories about the secret fund and about Bart Porter and Jeb Magruder, an FBI agent told Bernstein that the coverage had caused trouble inside the Bureau. L. Patrick Gray III, then acting director, had personally called the head of the Washington field office and ordered him to ensure that The Washington Post was not obtaining information from agents there. The episode revealed a tension between the Bureau’s investigative role and its leadership’s concern over leaks: the reporting had provoked an effort to determine whether agents were disclosing information.

That tension did not make every report based on investigative information reliable. In the disputed story asserting H. R. Haldeman’s control of the secret fund, the reporters altered the lead to attribute the claim not only to accounts of grand-jury testimony but also to federal investigators. Bob Woodward said an FBI agent had confirmed that investigators knew about the matter, and Deep Throat had likewise made clear that investigators knew. That confirmation did not establish the stronger claim that Haldeman had exercised authority over the fund or approved payments. The reporters later recognized that they had moved too quickly from a source’s account and their own deductions to a claim about Haldeman’s control. The FBI’s awareness of information and proof of the specific allegation were not the same thing.

Surveillance and National Security Claims

The FBI’s role in domestic wiretapping belonged to a broader policy adopted by the Nixon administration. Under the national-security wiretap policy known as the Mitchell Doctrine, the administration claimed authority to conduct electronic surveillance without court authorization against people suspected of domestic subversive activity. The Supreme Court declared the policy illegal on June 19, 1972, two days after the Watergate arrests. The dispute over who could be labeled subversive also raised a political question: critics argued that the term could be used for people who dissented too vigorously from administration policies.

Time magazine later published a detailed account of the administration’s campaign to trace news leaks through telephone taps. According to its report, the FBI had tapped the phones of six reporters and roughly twice as many White House and government aides for domestic-security reasons. The taps began in 1969 under J. Edgar Hoover and continued under his successor, L. Patrick Gray III, until the Supreme Court decision. Time reported that Hoover had permitted agents to install taps only after John Mitchell authorized each one in writing. It also described Hoover’s resistance, in 1971, to pressure to retire and reported that he threatened to disclose details of the wiretapping. These were claims made in the published account, not simply a description of the Bureau’s Watergate casework.

Later disclosures tied the leak investigation to a specific phone and to gaps in the government’s account. After the logs went missing, the new acting director, William D. Ruckelshaus, was told by aides that Daniel Ellsberg had been overheard at least once—not on Neil Sheehan’s phone, as first supposed, but on the home telephone of Morton Halperin, a former National Security Council staff member. Ruckelshaus announced that Halperin’s phone had been tapped for twenty-one months. This was the first confirmation that the administration had used wiretaps to investigate news leaks, and it established that the government had failed to disclose all wiretap information to Ellsberg’s defense attorneys.

Bob Woodward also received a direct confirmation from a senior FBI official that some wiretap authorizations had reached the Bureau orally or by letter from Henry Kissinger. The detail connected the surveillance program to senior officials while underscoring how authorization could travel through more than one channel. Together, the missing logs, the Halperin disclosure, and the confirmation about Kissinger’s authorizations widened the issue from a contested national-security policy to questions about documentation and disclosure in a criminal case.

Files, Oversight, and Institutional Accountability

The transfer and destruction of Watergate investigation files became another test of the Bureau’s independence. At Senate hearings that opened on February 28, L. Patrick Gray III described the investigation as an intensive effort and volunteered that he had turned its files over to John Dean. Gray said he could not guarantee that Dean had not shown the material to Donald Segretti. The disclosure placed FBI case files, and their handling by senior officials, at the center of public scrutiny.

Deep Throat later corroborated the substance of the account about Gray’s handling of files while supplying a more damaging explanation of the pressure surrounding them. He said that on June 28, in a meeting with John Ehrlichman and John Dean, Gray was told that the files were political dynamite and should never see the light of day. Deep Throat also reported that Ehrlichman had urged Dean to dispose of them across the river. According to this account, Gray kept the files for about a week and then put them in a burn bag in his office. Gray reportedly said he had not been explicitly instructed to destroy them, but understood that this was what Dean and Ehrlichman wanted. The account portrays the FBI director not as an autonomous custodian of investigative material, but as a participant under pressure from White House officials.

The Bureau’s institutional position was further complicated by the conduct of the Watergate investigation itself. Earl Silbert, the prosecutor, told the reporters that he expected to please no one and that there was no evidence to indict anyone beyond the seven men already caught. He described an unwritten evidentiary standard: the higher an investigator went, the more substantial the proof had to be. That caution provides context for the gap between investigative leads and provable responsibility. The FBI could identify connections, uncover surveillance, and assemble files, but what those findings established—and what prosecutors could act upon—depended on the quality of evidence and on whether the information survived the channels through which it passed.

Across the Watergate inquiry and the earlier leak investigation, the Bureau appears in several distinct capacities: as the agency tracing calls and interviewing campaign staff, as a source of information sought by reporters, as an organization whose agents were warned against leaking, and as a custodian of records vulnerable to political intervention. Its discoveries mattered, but so did the silences around them: a lead passed to Justice and not returned, records missing from the wiretap inquiry, and Watergate files transferred to a White House aide. The institution’s importance lies not in a single verdict about its conduct, but in the way its investigative reach and its exposure to outside pressure shaped what could be known and proved.
