Saw the clip on a PBS documentary with my dad, must have been 88 or so. Him saying there is tape in the Oval Office. Ninety nine years old. One sentence that ended a presidency.

Alexander Porter Butterfield was born on April 6, 1926, in Pensacola, Florida, to Susan Armistead Alexander Butterfield and United States Navy pilot (later Rear Admiral) Horace B. Butterfield. He grew up in Coronado, California, left home in 1943, and enrolled at the University of California, Los Angeles, where he became a friend of H. R. Haldeman and John Ehrlichman. He left UCLA to join the United States Air Force in 1948.
As a fighter pilot and officer, Butterfield taught fighter gunnery at what became Nellis Air Force Base, flew with the Skyblazers jet aerobatic team in Munich, commanded fighter units in Tennessee and Okinawa, and in Vietnam led a squadron of combat tactical air reconnaissance aircraft. He flew 98 combat missions and received the Distinguished Flying Cross. He later served as a military assistant at the Pentagon, spent substantial time at the White House, and by 1967 was the F-111 project officer and senior U.S. military representative in Australia. Along the way he attended the National War College and earned a B.S. from the University of Maryland (1956) and an M.S. from George Washington University (1967).
In late 1968, facing another tour in Australia and eager to be near the center of power, Butterfield wrote to his UCLA friend Haldeman, newly named Nixon's White House chief of staff. Haldeman offered him the role of deputy assistant to the president. Butterfield retired from the Air Force and took the post in January 1969. Next to Haldeman he became one of the most powerful aides in the White House: he controlled the paper flow to Nixon, planned the president's daily schedule, managed visitors, oversaw FBI background and political investigations requested by the White House, and for a time supervised First Lady Pat Nixon's staff and publicity.
In February 1971, on Nixon's order, Butterfield oversaw Secret Service installation of a secret voice-activated taping system in the Oval Office, Cabinet Room, and selected White House telephones. Only a handful of people knew it existed. In March 1973 Butterfield left the White House for the Federal Aviation Administration. On July 13, 1973, in a closed interview with Senate Watergate Committee staff, deputy minority counsel Donald Sanders asked whether conversations might have been recorded. Butterfield answered that there was tape in the Oval Office and explained how the system worked. He repeated the disclosure in televised public testimony on July 16. Historians later said the revelation transformed Watergate into a constitutional crisis that led to the fight over the tapes, the Saturday Night Massacre, and Nixon's resignation.
Butterfield was not charged in the cover-up. He had played a limited administrative role, including briefly safeguarding cash known as "the 350" for the re-election committee and arranging a Secret Service detail that Nixon hoped would monitor Senator Edward Kennedy. As FAA administrator from March 1973 to March 1975, he resigned his Air Force Reserve commission to meet the civilian requirement. President Gerald Ford later asked Nixon-era holdovers to leave; Butterfield resigned in March 1975. He struggled to find work for two years, then held posts in aviation and finance before founding the consulting firm Armistead & Alexander and retiring in 1995.
In later life Butterfield moved to La Jolla, California, earned an M.A. in history from the University of California, San Diego, and worked toward a Ph.D. on presidential pardon power. He was a major source for Bob Woodward's 2015 book The Last of the President's Men, based on extensive interviews and documents Butterfield kept from the White House. He correctly guessed Mark Felt as Deep Throat years before the 2005 disclosure. In 2022 he appeared on MSNBC with Lawrence O'Donnell, and Cassidy Hutchinson later cited his example when deciding to testify fully before the House January 6 Committee.
Butterfield married Charlotte Maguire in 1949; they divorced in 1985. She died in 2019. Their children were Alexander Porter Butterfield Jr. (a Navy captain who died in 2025), Susan Holcomb, and Lisa Buchholz. He was later married to Kim Butterfield, who with former White House counsel John Dean confirmed his death. He died at home in La Jolla on March 9, 2026, at age 99, a month shy of his 100th birthday. Wikipedia lists Arlington National Cemetery as his resting place.

In their own words
“I was wondering if someone would ask that. There is tape in the Oval Office.”
July 13, 1973, closed interview with Senate Watergate Committee staff, after Donald Sanders asked about John Dean's taping hypothesis (widely reported; Aaron Latham / committee accounts).
“Everything was taped... as long as the President was in attendance. There was not so much as a hint that something should not be taped.”
July 1973 testimony describing the White House taping system (quoted in Stanley Kutler and contemporaneous reports).
“Frankly, I don't like being known as the man who revealed the existence of the tapes. It makes it appear that I ran full tilt to the Watergate committee and told them eagerly and breathlessly the very information that Nixon considered top secret. That was not the case.”
Interview with The Washington Post, cited again in CNN and other 2026 obituaries.
“I hated to be the guy who had to tell about the tapes. But I saw these guys I really liked and admired going off to jail. And I realized Nixon exploited their loyalty.”
NPR StoryCorps conversation with Tom Johnson, aired September 30, 2022.
“I knew I would not lie. People were lying right and left. So I said if they asked me an absolutely direct question, I feel I will have no choice but to answer directly.”
NPR StoryCorps, 2022, explaining his decision before the Senate staff interview.
“I was aware of listening devices. Yes, sir.”
Public Senate Watergate Committee testimony, July 16, 1973, answering Fred Thompson.
“I think it was a guy named Mark Felt.”
Hartford Courant, December 17, 1995, correctly guessing Deep Throat's identity a decade before Felt's disclosure.
“Nixon was a very controlled person. He was so disciplined. He had a lot of hatreds and resentments of people. But he kept all that quite contained.”
NPR StoryCorps interview with Tom Johnson, 2022.

He always said he hated being known for it, which somehow made it hit harder.
