Warren Commission Report (National Archives)The U.S. Commission to Report upon the Assassination of President John F. Kennedy, established (Nov. 29, 1963) by executive order of President Lyndon B. Johnson, was directed to evaluate all the evidence and present a complete report of the event to the American people. The proceedings began December 3, 1963, and the final report was delivered to the President on September 24, 1964. During its investigation the commission weighed the testimony of 552 witnesses and the reports of 10 federal agencies, most important of which were the Secret Service, the Federal Bureau of Investigation, the Department of State, the Central Intelligence Agency, and military intelligence. The hearings were closed to the public unless the person giving testimony requested otherwise; only two witnesses made that request. The commission, in its findings, attempted to reconstruct the exact sequence of events of the assassination. Foremost among its conclusions was refutation of speculation that the assassination was part of a conspiracy, either domestic or foreign, or that any elements of the government had a hand in the event. The report maintained that Lee Harvey Oswald, acting alone and without accomplices, shot and killed the President and wounded Texas Governor John Connally from the sixth floor window of the Texas School Book Depository Building in Dallas on November 22, 1963.
