Article II of the United States Constitution

Article II establishes the executive power, which is the presidency.  Not until the 22nd Amendment was the presidency limited to two terms.  There are many guidelines set for the presidency:  Candidates must be at least 35 years old, and must have lived in the US for at least 14 years.  Should the President not be able to complete the duties of the office, then the vice president assumes the position of president.  A vice president who serves less than half of the presidency that s/he has taken over may run for another term as president.  This way, a person may serve a maximum of 10 years as president.  The 25th amendment states that the vice-president assumes the presidency upon the death or disability of the president.

The president is compensated for their duties.  George W. Bush made $600,000 yearly.  Article II prohibits pay increases while in office.  While the White House is the official residence of the president, the official residence of the vice-president is Number One Observatory Circle.

The president is the Commander in Chief of the armed forces.  S/he can also grant pardons or reprieves, but cannot pardon him/herself.  Provided that the Senate approves, the president can make treaties, appoint ambassadors, and judges to the Supreme Court.  Article II establishes the presidential oath.  In short, the oath concerns protecting the Constitution.

The president can be removed through impeachment.  When a president is impeached, they are not removed from office.  To be impeached is to be accused of a crime, and if found guilty, removed from office.
