President of the United States

The President of the United States(POTUS) is the head of state and the  head of the government of the United States of America. The president directs the Executive branch of the federal government and is the Commander-in Chief of the United States Armed Forces. In contemporary times, the United States President is looked upon by many as one of the world's most powerful political figures leading the greatest global superpower and a bastion for freedom.

The President’s role includes responsibility for the world's most expensive military, the second largest nuclear arsenal, and the largest economy by nominal GDP. The president possesses significant domestic and international power. Article II of the Constitution establishes the Executive branch of the federal government and vests the executive power of the United States in the President. The power includes the execution and enforcement of federal law, along with the responsibility of appointing federal executive, diplomatic, regulatory and judicial officers, and concluding treaties with foreign powers with the advice and consent of the Senate. 

The president is further empowered to grant federal pardons and reprieves, and to convene and adjourn either or both houses of Congress under extraordinary circumstances. The president directs the foreign and domestic policies of the United States, and takes an active role in promoting his policy priorities to members of Congress. In addition, as part of the system of checks and balances, Article I, Section 7 of the Constitution gives the president the power to sign or veto federal legislation.

Article II, Section 1, Clause 5 sets three qualifications for holding the presidency: natural-born U.S. citizenship; at least thirty-five years of age; and residency in the United States for at least fourteen years. 

The Twenty-second Amendment states that no person who has been elected to two presidential terms may be elected to a third. In all, 44 individuals have served 45 presidencies spanning 57 full four-year terms. Grover Cleveland served two non-consecutive terms, so he is counted twice.

Donald John Trump is the 45th and current president of the United States. He assumed office on January 20, 2017.
