Expulsion from the United States Congress

Expulsion is the most serious form of disciplinary action that can be taken against a Member of Congress. 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 processes for differ somewhat between the House of Representatives and the Senate.

Censure, a less severe form of disciplinary action, is an official sanction of a member that does not remove a member from office.

Presently, the disciplinary process begins when a resolution to expel or censure a Member is referred to the appropriate committee. In the House, this is the Committee on Standards of Official Conduct (House Ethics Committee); in the Senate, this is the Select Committee on Ethics (Senate Ethics Committee).

The committee may then ask other Representatives or Senators to come forward with complaints about the Member under consideration or may initiate an investigation into the Member's actions. Sometimes Members may refer a resolution calling for an investigation into a particular Member or matter that may lead to the recommendation of expulsion or censure.

Rule XI (Procedures of committees and unfinished business) of the Rules of the House of Representatives state that the Committee on Standards of Official Conduct can investigate allegations that a Member violated "any law, rule, regulation, or other standard of conduct applicable to the conduct of such Member... in the performance of his duties or the discharge of his responsibilities". The Senate Select Committee on Ethics has the same jurisdiction. The committee may then report back to their whole chamber as to its findings and recommendations for further actions.
