Article II of the United States Constitution vests executive power in the President, who is elected every four years and, as a result of the 22nd Amendment, can serve a maximum of two elected terms. As the ultimate executive authority, the President serves as “commander in chief” of the United States military, has the power (“with the advice and consent of the Senate”) to make treaties, and appoint judges and civil servants. The President also executes and enforces the laws of the United States and runs the day-to-day affairs of the government. Additionally, every President takes an oath to “preserve, protect, and defend” the U.S. Constitution., The United States Constitution, what it says, what it means, A Hip Pocket Guide (Oxford University Press)
