Article III of the Constitution states that judicial officers, or federal judges, are appointed for a life term. A federal judge may also end their term by resigning.
Judges, including those on the Supreme Court, Court of Appeals and district court, are all appointed by the President of the United States of America. Once they are appointed, the Constitution states that the United States Senate must approve their appointment. The Senate Judiciary Committee typically conducts confirmation hearings for the nominees. Often times, senators and other politicians that are members of the President's political party make recommendations for potential federal judges.
