The testimony of Roy Eugene Vaughn was taken at 9:10 a.m., on April 17, 1964, in the office of the U.S. attorney, 301 Post Office Building, Bryan and Ervay Streets, Dallas, Tex., by Mr. Leon D. Hubert, Jr., assistant counsel of the President's Commission.
Mr. Hubert. Mr. Vaughn, my name is Leon Hubert. I'm a member of the advisory staff of the general counsel of the President's Commission. Under the provisions of Executive Order 11130, dated November 29, 1963, and the joint resolution of Congress No. 137, and the rules of procedure adopted by the Commission in conformance with the Executive order and joint resolution, I have been authorized to take a sworn statement from you.
I state to you now that the general nature of the Commission's inquiry is to ascertain, evaluate, and report upon facts relating to the assassination of President Kennedy and the subsequent violent death of Lee Harvey Oswald.
In particular to you, Mr. Vaughn, the nature of the inquiry today is to determine what facts you know about the death of Oswald and any other pertinent facts you may know about the general inquiry, and more particularly about the entry or possible entry of Ruby into the basement through the Main Street ramp. Did you get a letter directed to you?
Mr. Vaughn. To appear here?
Mr. Hubert. Yes.
Mr. Vaughn. Yes, sir.
Mr. Hubert. That letter was a written request, written by Mr. J. Lee Rankin, General Counsel of the Commission, to you asking you to appear; is that correct?
Mr. Vaughn. Yes.
Mr. Hubert. Was that letter received by you more than 3 days from this day?
