The Reorganization Act of 1939, Pub.L. 76–19, 53 Stat. 561, enacted April 3, 1939, codified at 5 U.S.C. § 133, is an American Act of Congress which gave the President of the United States the authority to hire additional confidential staff and reorganize the executive branch (within certain limits) for two years subject to legislative veto. It was the first major, planned reorganization of the executive branch of the government of the United States since 1787. The Act led to Reorganization Plan No. 1, which created the Executive Office of the President.
