FBI surveillance of Martin Luther King Jr.
The FBI wiretapped Martin Luther King Jr., bugged his hotel rooms, and in 1964 mailed him an anonymous letter urging him to kill himself. The Attorney General had authorised the wiretaps. The Bureau kept the operation running until his death.
Why this verdict
Confirmed by the Church Committee, by court-ordered release of the surveillance authorisations, and by the unredacted 1964 FBI letter held at the National Archives.

01The claim
That the federal government used its full surveillance capability against the most prominent civil rights leader in the country, not to investigate a crime but to discredit him personally and break his influence.
02Where it came from
J. Edgar Hoover's interest began with the Montgomery bus boycott and hardened into an obsession. The formal justification was an alleged communist influence on King through advisers Stanley Levison and Jack O'Dell — a claim the Bureau pursued for years and never substantiated. In October 1963 Attorney General Robert Kennedy authorised wiretaps on King's home and on the offices of the Southern Christian Leadership Conference. The Bureau then went considerably further than the authorisation, planting microphones in hotel rooms in at least a dozen cities.
03What the record shows
✓ CONFIRMED — It happened. The documents exist.
The Church Committee devoted a full report to the King operation and concluded that the FBI had attempted to discredit and neutralise him. The central artefact is a letter mailed anonymously to King in November 1964, shortly after he was named a Nobel laureate, accompanied by a tape of hotel room recordings. An unredacted copy surfaced in the National Archives in 2014. It tells King he is a fraud, that 'you are done', and gives him thirty-four days to act — timed, King's associates believed, to the Nobel ceremony. Coretta Scott King and colleagues understood it as an instruction to take his own life.
The authorship is not in doubt: the Church Committee traced the letter to the FBI's Domestic Intelligence Division, and the accompanying tape to Bureau surveillance. In 1977 a federal judge ordered all King surveillance tapes and transcripts sealed in the National Archives until 2027, on privacy grounds — meaning the full record of what the Bureau collected is still closed.
Separately, the Bureau circulated derogatory material about King's private life to journalists, foundations and government officials, including an attempt to prevent his receipt of an honorary degree.
04What it cost
The King operation is the most concrete demonstration of what COINTELPRO meant in practice, and it is the reason the phrase 'the FBI investigated him' carries a permanent shadow in American civil rights history. It contributed directly to the 1976 Attorney General guidelines restricting investigations based on political speech. It also seeded lasting distrust of official accounts of King's assassination — a 1999 Memphis civil jury found for the King family in a wrongful death suit alleging a conspiracy, while a 2000 Justice Department review found no evidence supporting that verdict.
