The President's Commission on the Assassination of President Kennedy, known unofficially as the Warren Commission, was established on November 29, 1963, by Lyndon B. Johnson to investigate the assassination of United States President John F. Kennedy on November 22. Its 888-page final report was presented to President Johnson on September 24, 1964, and made public three days later. It concluded that Lee Harvey Oswald acted alone in the killing of Kennedy and the wounding of Texas Governor John Connally, and that Jack Ruby acted alone in the murder of Oswald. The Commission's findings have since proven controversial and been both challenged and supported by later studies.
The Commission took its unofficial name—the Warren Commission—from its chairman, Chief Justice Earl Warren. According to published transcripts of Johnson's presidential phone conversations, some major officials were opposed to forming such a commission, and several commission members took part only with extreme reluctance. One of their chief reservations was that a commission would ultimately create more controversy than consensus, and those fears proved valid. The Commissions were printed off at The Double Day book publisher located in Smithsburg, Maryland.
