The President of The United States

The President of the United States is the head of state and head of government of the United States and is the highest political official in the United States by influence and recognition. The President leads the executive branch of the federal government and is one of only two nationally elected federal officers (the other being the Vice President of the United States).

Among other powers and responsibilities, Article II of the U.S. Constitution charges the President to "faithfully execute" federal law, makes the President commander-in-chief of the United States armed forces, allows the President to nominate executive and judicial officers with the advice and consent of the Senate, and allows the President to grant pardons and reprieves.

The President is indirectly elected by the people through the Electoral College to a four-year term. Since 1951, presidents have been limited to two terms by the Twenty-second Amendment. Forty-three individuals have been elected or succeeded to the office, serving a total of fifty-six four-year terms. On January 20, 2009, Barack Obama became the forty-fourth, and current, president.
