The Executive Branch of the federal government consists of the office of the President and Vice President, the Executive Office of the President (the “West Wing”), fifteen departments whose heads serve in the Cabinet and, according to the Federal Registrar, 440 federal agencies. In total, there are about 2.8 million federal government employees.
The powers of the US President are limited. The President is the Commander-in-Chief of the armed forces, a constitutional role that assures civilian oversight of the US military, but only congress can declare war or provide funding for conflicts short of an outright declaration of war.
The President has the power to sign or veto any legislation, but a veto can be overturned with a two-thirds vote in both the House and Senate. The President is also empowered to negotiate treaties and trade agreements with foreign governments, but the Senate must approve by a two-thirds vote.
The President also appoints all federal judges and all key executive branch officials, again with the requirement for Senate approval for all judges and all cabinet heads.
Presidents also have the power to issue Executive Orders, without legislative approval, which become the law of the land unless overturned in the Supreme Court or a law passed through congress. This power comes from two sources. First, there is the “executive powers” clause of the constitution. Second, over time a wide variety of laws passed by the legislature have explicitly granted the President this power, particularly in the area of national security.
Historically, Presidents have been reluctant to use this power widely. George Washington issued eight and John Adams one. The record goes to Franklin Roosevelt, who issued 3,522, followed by Woodrow Wilson at 1,863. Our last two Presidents, George Bush and Barak Obama, issued 291 and 260, respectively.
The primary role of the Vice President is to stand ready to replace the President upon death or disability. The Vice President also serves as President of the Senate, but only votes to break a tie. The real leader of the Senate is the President Pro Temp, a Senator elected by the members of the Senate.
The Executive Office of the President was originally established by Franklin Roosevelt is 1939 to add professional management depth to the office. Today, this office has about 1,800 employees. Included in the Executive Office are the Chief of Staff, Office of Management and Budget, the Council of Economic Advisors, the National Security Council and the Press Secretary.
