Martin Luther King Jr. FBI File: What's Actually in the Declassified Records

Short answer

Martin Luther King Jr. was the target of one of the FBI's most aggressive domestic surveillance campaigns. Under J. Edgar Hoover's direction, the Bureau monitored King for over a decade, wiretapped his phones, bugged his hotel rooms, and ran a COINTELPRO operation designed to discredit and destabilize him. The FBI sent King an anonymous package containing a letter widely interpreted as urging him to commit suicide. No evidence of Communist control was ever found.

Why there is a file

The FBI began monitoring King in 1956 after he emerged as a leader of the Montgomery Bus Boycott. By 1962, FBI Director J. Edgar Hoover had become fixated on King's relationship with Stanley Levison, an advisor the Bureau identified as a former Communist Party member. Attorney General Robert Kennedy authorized wiretaps on King's home and SCLC offices in October 1963. Rather than investigating alleged Communist influence, the FBI shifted to a campaign aimed at undermining King himself. Hoover publicly called King 'the most notorious liar in the country' in November 1964. Around the same time, the FBI anonymously mailed King a package containing a compromising tape recording and a letter that King and his staff interpreted as urging him to commit suicide. In 1967, King was formally designated a target under COINTELPRO's 'Black Nationalist–Hate Groups' program, which sought to prevent the rise of a leader who could unify the civil rights movement. After King's assassination on April 4, 1968, the FBI conducted the murder investigation (codenamed MURKIN), ultimately concluding that James Earl Ray acted alone.

What people often get wrong

  • ✗"The FBI was protecting King." The opposite is true. The FBI ran an active campaign to discredit, destabilize, and neutralize King. The Bureau's own records show it viewed him as a threat to be eliminated from public life.
  • ✗"The surveillance was justified because of Communist infiltration." The FBI never found evidence that King was controlled by or working for the Communist Party. A Senate investigation later concluded the Bureau targeted King himself rather than any alleged Communist influence.
  • ✗"The FBI file is fully public." Significant portions remain classified. Surveillance tapes recorded in King's hotel rooms are sealed at the National Archives until 2027 under a court order.
  • ✗"The FBI only watched King from a distance." The Bureau placed informants inside SCLC, bugged hotel rooms, wiretapped phones, and sent anonymous communications designed to destroy King's marriage and career.
