To develop new legislation governing the use of atomic energy in the United States, the U.S. Senate created a Special Committee that held a series of public hearings in late 1945 and early 1946. In his testimony on 28 November 1945, General Leslie Groves discussed the scope of the Manhattan Project, the problem of international control, and the destructive effects of atomic explosions. He did not provide a factual account of radiation effects, however, although the information provided by Stafford Warren would have made reasonably informative answers entirely possible, but Groves may not have had time to assimilate it. Perhaps wanting to preserve secrecy or possibly unwilling to admit uncertainty, Groves made bizarre and misleading statements to the Senators.
