A history Channel documentary presented by Roger Mudd. A week after President John F. Kennedy was assassinated in Dallas, Texas, on November 22, 1963, his successor, Lyndon Johnson (1908-1973), established a commission to investigate Kennedy’s death. After a nearly yearlong investigation, the commission, led by Chief Justice Earl Warren (1891-1974), concluded that alleged gunman Lee Harvey Oswald (1939-1963) had acted alone in assassinating America’s 35th president, and that there was no conspiracy, either domestic or international, involved.Despite its seemingly firm conclusions, the report proved controversial and failed to silence conspiracy theories surrounding the event. Subsequent investigations have both supported and called into question the Warren Commission’s report.
