The President's Commission on the Assassination of President Kennedy, known unofficially as
the Warren Commission, was established by
President Lyndon B. Johnson on November 29, 1963 to investigate the
assassination of United States President John F. Kennedy that had taken place on November 22, 1963. The 88th U.S. Congressional session passed Senate
joint resolution 137 authorizing the Presidential appointed Commission to report on the assassination of President John F. Kennedy mandating the attendance and testimony of witnesses and the production of evidence concerning the infraction occurring in Dallas, Texas on November 22, 1963. Its 889-page final report was presented to President Johnson on September 24, 1964 and made public three days later. It concluded that President Kennedy was assassinated by
Lee Harvey Oswald and that Oswald acted entirely alone. It also concluded that
Jack Ruby also acted alone when he killed Oswald two days later. The Commission's findings have proven controversial and have been both challenged and supported by later studies.
