On November 29, 1963, President Lyndon B. Johnson signed Executive Order No. 11130, creating a Commission "to ascertain, evaluate and report upon the facts relating to the assassination of the late President John F. Kennedy and the subsequent violent death of the man charged with the assassination." By the same Executive order, the President appointed seven Commissioners: Earl Warren, Chief Justice of the United States; Richard B. Russell, Democratic Senator from Georgia; John Sherman Cooper, Republican Senator from Kentucky; Hale Boggs, Democratic Congressman from Louisiana and House Majority Whip; Gerald R. Ford, Republican Congressman from Michigan; Allen W. Dulles, former Director of the Central Intelligence Agency; and John J. McCloy, former High Commissioner of Germany. The President designated Chief Justice Warren as the Commission's Chairman. The findings of the Commission, based on an examination of all the facts, are set forth in the separate volume entitled "Report of the President's Commission on the Assassination of President Kennedy." An essential part of the investigation conducted by this Commission has been the securing of sworn testimony from witnesses possessing information relevant to the inquiry. This testimony has been taken under the authority of Senate Joint Resolution 137 (88th Cong., 1st sess.), enacted by Congress on December 13, 1963, which conferred upon the Commission the power to administer oaths and affirmations, examine witnesses, receive evidence, and issue subpenas. Under the procedures adopted by the Commission, some witnesses have appeared before members of the Commission, others have been questioned under oath on depositions by members of the staff, and others have provided affidavits to the Commission. Beginning with its first witness on February 3, 1964, the Commission under these procedures took the testimony of approximately 550 witnesses and received more than 3,100 exhibits into evidence. The testimony and exhibits obtained by the Commission are printed in this and the succeeding volumes, organized in the following order: (1) Testimony before members of the Commission, in the order in which it was taken. (2) Testimony by sworn deposition or affidavit, grouped into four general subject categories; the medical attention given to the President and the Governor, identification of the assassin of President Kennedy, the background of Lee Harvey Oswald, and the killing of Lee Harvey Oswald by Jack L. Ruby on November 24, 1963. (3) Exhibits introduced in connection with the testimony before the Commission in numerical order. (4) Exhibits introduced in connection with sworn depositions and affidavits, grouped alphabetically by name of witness. (5) Other exhibits introduced before the Commission in numerical order.
