Alexander Butterfield reveals the White House taping system

Alexander Butterfield reveals the White House taping system in a disclosure that changed the evidentiary stakes of the Watergate investigation: Richard Nixon’s conversations had been recorded, and the resulting tapes could bear directly on what the President and his aides knew. The revelation emerged through an inquiry into Butterfield’s duties, was first relayed privately to Bob Woodward, and then entered public view when Butterfield testified before the Senate committee on national television.

The Question Behind the Interview

The route to the disclosure began with an unresolved detail in Butterfield’s White House responsibilities. Some weeks before the Senate staff interviewed him, Woodward had asked another staffer why Butterfield’s duties in H. R. Haldeman’s office were described as internal security. The staffer did not know the answer but suggested Butterfield might be worth interviewing. He said he would raise the idea with Sam Dash, the committee’s chief counsel. Dash initially put the matter off; only after the staffer pressed again did Dash approve an interview for Friday, July 13, 1973.

The question was narrow, and the staff’s uncertainty about it mattered. The committee had not set out, on the evidence recounted here, with knowledge of a presidential recording system. It was following a clue about an aide’s job description. That ordinary investigative step brought committee staff into contact with information that had been tightly restricted within the White House. The interval between the first suggestion and the eventual interview also shows that the disclosure was not the result of an already organized public inquiry into the tapes: the subject had not yet been recognized as the reason Butterfield’s duties might matter.

A Private Disclosure and a Reluctant Witness

On Saturday, July 14, Woodward received a call at home from a senior member of the committee’s investigative staff. The caller congratulated him and said the committee had interviewed Butterfield, who had told the whole story. When Woodward asked what that meant, the staff member answered, “Nixon bugged himself.” The blunt phrase condensed the revelation: the President’s conversations had been monitored by a system operating inside the White House.

The staff member described the interview as an exchange in which only junior staff members had been present. Near its end, someone read an excerpt from John Dean’s testimony about a meeting with Nixon on April 15. Dean had recalled that Nixon rose from his chair, went behind it to a corner of his Executive Office Building office, and spoke so quietly that he was barely audible. Nixon said he might have been foolish to discuss E. Howard Hunt’s clemency with Charles Colson. Dean’s recollection included his own thought that the room might be bugged. That testimony supplied a specific reason for the interviewers to press the question of whether a recording system existed.

Butterfield did not volunteer the information as an eager witness. He was reluctant because he understood that the President would not want the system’s existence disclosed. The investigators pressed him, and the subject came into view despite his hesitation. The episode’s force lies partly in that contrast: a detail of office security opened onto a system of presidential recording, while the person positioned to confirm it recognized the political sensitivity of doing so.

What the System Meant—and What Reporters Withheld

The system’s existence had been known only to Nixon, Haldeman, Larry Higby, Alexander Haig, Butterfield, and the Secret Service agents who maintained it. Even after Butterfield disclosed it to committee staff, the information was initially strictly off the record. The revelation was therefore not immediately treated as publishable news. Woodward and his colleagues considered the possibility that the disclosure itself could be turned against the investigation: Nixon might provide doctored or manufactured tapes to clear himself and his aides, or recorded conversations might be used to make it appear that he had learned incriminating information only from others.

Those concerns led the reporters to hold back rather than pursue the story at once. Butterfield had also said that even Henry Kissinger and John Ehrlichman did not know about the system, a detail that reinforced both its restricted reach and the difficulty of understanding how recordings might be used. Woodward spent Saturday night thinking about the implications. The question was no longer simply whether tapes existed. It was whether they could be obtained, whether they would be complete and reliable, and what they might establish about conversations at the center of the investigation. The disclosure thus created a new evidentiary possibility while leaving open the problem of access and proof.

Public Testimony and the Tapes’ Aftermath

The Senate committee moved quickly after the private interview. On Monday, Butterfield reluctantly laid out the story of the tapes before the committee and the country on national television. What had been an off-the-record disclosure to investigative staff became a public fact through Butterfield’s own testimony. The next morning, Ben Bradlee’s response to the developing story—“It’s more than a B-plus.”—registered the importance the newsroom attached to what had come out.

The public disclosure gave investigators and the country a concrete reason to seek presidential recordings. Its implications soon became entangled with the confrontation over access to them. In the later sequence described in the book, Archibald Cox subpoenaed nine presidential tape recordings. After Nixon fired Cox, Attorney General Elliot Richardson and his deputy, William Ruckelshaus, resigned. Nixon subsequently surrendered seven tapes under public pressure and a court order; his lawyers said that two of the subpoenaed recordings had never existed. That later conflict did not establish in advance what any recording would prove, but it made the system’s existence central to the struggle over evidence.

Butterfield’s testimony was therefore more than an account of a hidden technical arrangement. It altered the investigation’s horizon: investigators could now seek direct records of conversations rather than depend solely on witnesses’ recollections and accounts. At the same time, the delay between private disclosure and public testimony, and the subsequent fight over the tapes, showed that discovering evidence and securing it were separate problems. The revelation opened that second contest, in which presidential recordings became a focus of the Watergate crisis.
