Mr. Johnson. Oh, because I felt dutybound to cooperate in the full with the Government in any investigation of this assassination.
Mr. Rankin. Do you know whether or not Lee Harvey Oswald was ever a member of the Communist Party of the United States of America?
Mr. Johnson. To my knowledge, he was never such, and I would know.
Mr. Rankin. You think you would know?
Mr. Johnson. Oh, yes; I would, I am sure.
Mr. Rankin. I hand you an exhibit that has been marked——
Mr. Liebeler. Exhibit No. 1 on the examination of Arnold Johnson, April 17, 1964. It has been our practice for the examining attorney and for the witness to initial the exhibit for purposes of identification so there is no confusion.
Mr. Rankin. Mr. Johnson, would you be kind enough to initial the exhibit under my initials so we both certify one of the exhibits offered.
Mr. Johnson. Yes (witness complies).
(Document marked Johnson Exhibit No. 1.)
