In 1921 the Bureau of the Budget was established as part of the U.S. Department of the Treasury, according to the Accounting Act. The Treasury Department continued overseeing the budget office until 1939, when the Executive Office of the President (EOP) was given authority over the bureau. In 1970, during the Nixon administration, the Bureau of the Budget was reorganized and renamed the Office of Management and Budget (OMB). In the 1990s, it was further reorganized to combine management and budgetary staff responsibilities under the heading of the various Resource Management Offices.
