What does the President do?

The President enforces federal laws, commands the United States military as Commander in Chief, conducts foreign policy, appoints federal officials, and serves as the head of state. Article II of the Constitution sets out these powers and adds that the President shall take care that the laws be faithfully executed. As chief executive, the President directs the federal agencies that carry out laws, from the Internal Revenue Service collecting taxes to the Environmental Protection Agency enforcing pollution standards. The President can issue executive orders directing how agencies implement laws, though those orders must operate within the boundaries of statutes passed by Congress and the Constitution.

As Commander in Chief, the President has supreme authority over the armed forces. The President can deploy troops, order military operations, and make strategic decisions about national defense. Only Congress can formally declare war, but presidents have committed forces to combat many times without a declaration, including in Korea, Vietnam, the Persian Gulf, Afghanistan, and Iraq. The War Powers Resolution of 1973 requires the President to notify Congress within 48 hours of committing forces and to withdraw them within 60 days unless Congress authorizes continued action, though presidents have often disputed its constitutionality.

In foreign policy, the President negotiates treaties (subject to Senate ratification by a two-thirds vote), appoints ambassadors, receives foreign diplomats, and represents the United States abroad. The President also leads federal trade and economic diplomacy. The President's appointment power covers federal judges, including Supreme Court justices, ambassadors, Cabinet secretaries, and thousands of other senior federal officials. Senate confirmation is required for the most important posts.

The President also has the power to grant pardons for federal crimes (but not state crimes or impeachment cases) and to veto legislation passed by Congress. A two-thirds vote in each chamber overrides a presidential veto. Beyond these constitutional powers, the President serves as the public face of the United States, gives the State of the Union address each year, and shapes the national political agenda through speeches, press conferences, and policy initiatives.
