The Testimony subseries includes Forrestal's text for testifying before committees of Congress while he was Under Secretary of the Navy, Secretary of the Navy, and Secretary of Defense. Forrestal most commonly testified before the Naval Affairs or appropriations committees, and after 1948 before the Armed Services Committee. As Under Secretary of the Navy, Forrestal testified about Navy contracts with private industry and the production and procurement of ships and equipment. While he was Secretary of the Navy, the most common issues he testified about were appropriations for the Navy, the need for universal military training, and the proposed unification of U.S. military branches. While he was Secretary of Defense, his testimony continued to center on the unification of the military and on appropriations for the National Military Establishment (NME), as well as the Marshall Plan, universal military training, and the naval building program. Also included is a small amount of Forrestal's testimony before the Committee on Banking and Currency in 1933 regarding stock exchange practices while he still worked at William A. Read and Company on Wall Street.
