officially President's Commission on the Assassination of President John F. Kennedy
(1963–64) Group appointed by Pres.
Lyndon B. Johnson to investigate the circumstances surrounding John F. Kennedy 's slaying and the shooting of his assassin, Lee Harvey Oswald . It was chaired by Earl Warren and included two U.S. senators, two U.S. congressmen, and two former public officials. After months of investigation, it reported that Kennedy was killed by Oswald's rifle shots from the Texas School Book Depository and that Oswald's murder by Jack Ruby two days later was not part of a conspiracy to assassinate Kennedy. Its findings were later questioned in a number of books and articles and in a special congressional committee report in 1979, though no conclusive contradictory evidence was found.
