WASHINGTON (AP) — Alexander Butterfield, the White House aide who inadvertentlyhastened Richard Nixon’s resignationoverthe Watergate scandalwhen he revealed that the president had bugged the Oval Office and Cabinet Room and routinely recorded his conversations, has died. He was 99.

His death was confirmed to The Associated Press by his wife, Kim, and John Dean, who served as White House counsel to Nixon during the Watergate scandal and went on to, along with Butterfield, helpexpose the wrongdoing.

“He had the heavy responsibility of revealing something he was sworn to secrecy on, which is the installation of the Nixon taping system,” Dean said. “He stood up and told the truth.”

As a deputy assistant to the president, Butterfield oversaw the taping system connected to voice-activated listening devices that had been secretly placed in four locations, including Nixon’s office in the Executive Office Building and the presidential retreat at Camp David.

Butterfield later said that, besides himself and the president, he believed that only White House chief of staff H.R. Haldeman, a Haldeman assistant and a handful of Secret Service agents knew about the taping system.

“Everything was taped … as long as the president was in attendance,” Butterfield told Watergate investigators when testifying under oath during a preliminary interview.

The tapes would expose Nixon’s role in the cover-up that followed the burglary in 1972 at the Democratic Party headquarters at the Watergate building. To avoid impeachment by the House, Nixon resigned on Aug. 9, 1974, less than a month after the Supreme Court had ordered him to surrender the relevant tapes to the Watergate special prosecutor.

Butterfield believed he’d had a hand in the president’s fate. “I didn’t like to be the cause of that, but I felt that I was, in a lot of ways,” he said in a 2008 oral history for the Nixon Presidential Library and Museum.

Butterfield, a college friend of Haldeman’s at UCLA who had contacted his friend to ask about opportunities in the new Nixon administration, served as a deputy assistant to Nixon from 1969 to 1973. In that capacity, he worked under Haldeman and, among other duties, was secretary to the Cabinet and helped oversee White House operations.

The Air Force veteran had left the White House to become administrator of the Federal Aviation Administration when Senate committee staffers privately questioned him on July 13, 1973, during their investigation of the Watergate break-in. A routine question about the possibility of a taping system had been prompted by former White House counsel John Dean’s testimony that he believed a conversation he had had with Nixon may have been recorded.
