Executive Office of the President: An Historical Overview [Updated March 17, 2008] [open pdf - 179KB]
"Established in 1939, the Executive Office of the President (EOP) consists of a group of federal agencies immediately serving the President. Among the oldest of these are the White House Office, where many of the President's personal assistants are located, and the Office of Management and Budget, which was established as the Bureau of the Budget in 1921 and by transfer became one of the original EOP units in 1939. Entities have been placed within the EOP by both presidential action and congressional determination. Some components have endured; others have been brief experiments. Some have been transferred to other quarters of the executive branch; others have been abolished with no successor. In large measure, the tenure and durability of an Executive Office agency is dependent upon its usefulness to the President - as a managerial or coordinative auxiliary, a national symbol, or a haven of political patronage, among other considerations. This report reviews the particular circumstances of the creation of, and underlying authority for, the Executive Office of the President, and provides profiles of the entities that have been, and still are, located within that enclave."
