President Lyndon Johnson asked Chief Justice Earls Warren to investigate the assassination of President Kennedy.
President Johnson issued an executive order to create a special commission to investigate JFK's assasination. This commission was integrated by seven members, but it soon became known as the Warren Commission after the name of the group's chairman Chief Justice Earl Warren.
The final Warren Commission report was delivered to President Johnson on September 24, 1964 and concluded that Lee Harvey Oswald had been the lone assassin of President Kenedy and that there was no conspiracy.
