Newly-released documents reveal the full extent of the FBI’s surveillance of the civil rights leader Dr Martin Luther King in the mid-1960s. They expose in graphic detail the FBI’s intense focus on King’s extensive extramarital sexual relationships with dozens of women, and also his presence in a Washington hotel room when a friend, a Baptist minister, allegedly raped one of his “parishioners”, while King “looked on, laughed and offered advice”. The FBI’s tape recording of that criminal assault still exists today, resting under court seal in a National Archives vault.

The FBI documents also reveal how its Director, J. Edgar Hoover, authorised top Bureau officials to send Dr King a tape-recording of his sexual activities along with an anonymous message encouraging him to take his own life.

The complete transcripts and surviving recordings are not due to be released until 2027 but when they are made fully available a painful historical reckoning concerning King’s personal conduct seems inevitable.
