FBI's anonymous letter to Martin Luther King Jr.

1964Contested

In November 1964 the FBI mailed Martin Luther King Jr. an anonymous letter, with a tape of secretly recorded hotel rooms, that threatened exposure and appeared to urge him to kill himself.

The story

In November 1964, weeks before Martin Luther King Jr. was to receive the Nobel Peace Prize, the FBI mailed a package to the headquarters of his Southern Christian Leadership Conference in Atlanta. It held a reel of audio recorded by FBI bugs in hotel rooms where King had stayed and an unsigned letter, written as if by a disillusioned Black supporter, calling him a fraud and threatening to expose him. It ended with the words that there was only one thing left for him to do, which King and his aides read as an invitation to suicide. Coretta Scott King opened the package in January 1965.

The letter came out of the FBI's long campaign against King, which Director J. Edgar Hoover pursued with wiretaps approved by Attorney General Robert Kennedy in 1963 and with bugs the FBI planted on its own. Assistant Director William Sullivan, who ran the bureau's domestic intelligence division, is widely believed to have written it. The Church Committee revealed the letter's existence in 1975, and in 2014 historian Beverly Gage found a nearly unredacted copy in the National Archives and published it in The New York Times Magazine.

Why it mattered

  • The letter became the single most notorious example of the FBI's covert war on the civil rights movement.
  • Its exposure by the Church Committee helped lead to guidelines restricting FBI domestic intelligence in 1976.
  • The 2014 publication of the unredacted text renewed debate about surveillance of activists during the Snowden era.

Contested history

Consensus: The Church Committee and the FBI's own files confirm the bureau sent the anonymous letter and tape. Its wording and authorship are documented; whether it was meant literally as a suicide demand is a matter of reading.

The FBI wrote and mailed the anonymous letter to KingEstablished
The Church Committee documented the operation, and the original draft was found in FBI files held by the National Archives.
The letter urged King to kill himselfDebated
King, his aides and most historians read the closing lines as an invitation to suicide. A minority of commentators argue it was meant to pressure him to withdraw from public life before the Nobel ceremony.
William Sullivan wrote the letterDebated
Historians including Beverly Gage attribute it to Sullivan based on FBI records and his role; Sullivan never admitted writing it and no signed draft has been found.
The surveillance behind the letter shows the danger of unchecked domestic spyingMatter of opinion
Civil liberties groups cite the letter as a warning about surveillance powers, while others treat it as an aberration of the Hoover era corrected by later reforms.
