<P> Within the executive branch itself, the president has broad powers to manage national affairs and the priorities of the government . The president can issue rules, regulations, and instructions called executive orders, which have the binding force of law upon federal agencies but do not require approval of the United States Congress . Executive orders are subject to judicial review and interpretation . </P> <P> The Budget and Accounting Act of 1921 put additional responsibilities on the presidency for the preparation of the United States federal budget, although Congress was required to approve it . The act required the Office of Management and Budget to assist the president with the preparation of the budget . Previous presidents had the privilege of impounding funds as they saw fit, however the United States Supreme Court revoked the privilege in 1998 as a violation of the Presentment Clause . The power was available to all presidents and was regarded as a power inherent to the office . The Congressional Budget and Impoundment Control Act of 1974 was passed in response to large - scale power exercises by President Nixon . The act also created the Congressional Budget Office as a legislative counterpoint to the Office of Management and Budget . </P> <P> The president has several options when presented with a bill from Congress . If the president agrees with the bill, he can sign it into law within ten days of receipt . If the president opposes the bill, he can veto it and return the bill to Congress with a veto message suggesting changes unless the Congress is out of session then the president may rely on a pocket veto . </P> <P> Presidents are required to approve all of a bill or none of it; selective vetoes have been prohibited . In 1996, Congress gave President Bill Clinton a line - item veto over parts of a bill that required spending federal funds . The Supreme Court, in Clinton v. New York City, found Clinton's veto of pork - barrel appropriations for New York City to be unconstitutional because only a constitutional amendment could give the president line - item veto power . </P>
