Who can punish members of the house for disorderly behavior

Expulsion and Censure. 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."

The House of Representatives.

Both the House and the Senate have the power to punish their own members for diorderly behavior and small infractions. It would take a two-thirds vote in either legislative house to expel or fire a representative.

These rules are found in Expulsion and Censure Article 1 Section 5 of the Constitution.
