The President is the head of state and head of government of the United States. Elected by the Electoral College every four years, the President may serve no more than two terms. The President heads the executive branch of the government, having thousands of unelected employees like bureaucrats or the military.
The President of the United States may sign into law legislation that has been approved by Congress or veto it. He chooses a cabinet to advise him on specific issues. While the president of the United States has less power than many of his foreign counterparts, he is seen as the embodiment of the United States and its international image. Many presidents propose legislation and serve to influence Congress to make progress in a certain direction.
The first president of an independent United States was George Washington, and the current president is Barack Obama. Including Obama, there have been 44 presidents. The most famous include Abraham Lincoln, Franklin D. Roosevelt, John F. Kennedy and Ronald Reagan.
