Article I, section 5 of the United States Constitution provides that "Each House [of Congress] may determine the Rules of its proceedings, punish its members for disorderly behavior, and, with the concurrence of two-thirds, expel a member."
Since 1789 the Senate has expelled only 15 members. Of that number, 14 were expelled during the Civil War for supporting the Confederacy. In several other cases, the Senate considered expulsion but either dropped those proceedings or failed to act before the member left office. In those cases, corruption was the primary cause of complaint.
