EXECUTIVE OFFICE OF THE PRESIDENT
Under authority of the Reorganization Act of 1939 (5 U.S.C. 133-133r,
133t note), various agencies were transferred to the Executive Office of
the President by the President's Reorganization Plans I and II of 1939
(5 U.S.C. app.), effective July 1, 1939. Executive Order 8248 of
September 8, 1939, established the divisions of the Executive Office and
defined their functions. Subsequently, Presidents have used Executive
orders, reorganization plans, and legislative initiatives to reorganize
the Executive Office to make its composition compatible with the goals
of their administrations.
