Article II of the US Constitution

The executive branch of the United States government is established by Article Two of the Constitution, which vests the power in the office of the President. The President and Vice President serve four-year terms and are elected through the Electoral College, with each state choosing electors equal to their combined representation in both houses of Congress. The President is Commander-in-Chief of the military and has the power to grant pardons, while also being responsible for taking an oath of office. The President has the authority to appoint judges and public officials with the advice and consent of the Senate, and can make recess appointments when the Senate is in recess. The President is also responsible for convening both Houses of Congress, receiving foreign representatives, and commissioning federal officers, and is required to inform Congress of the state of the union and recommend measures deemed necessary and expedient. The President can be removed from office through impeachment for treason, bribery, or other high crimes and misdemeanors.learn more on wikipedia
