How a judge gets here. Each judge is nominated by a president and confirmed by the U.S. Senate, then holds a numbered seat, for life, until they take senior status, or until they leave the bench. Open any judge to see who appointed them, how the Senate voted, and whom they succeeded, a chain that runs back to 1789.
