The U.S. Senate has developed procedures for taking disciplinary action against senators through such measures as formal censure or actual expulsion from the Senate. The Senate has two basic forms of punishment available to it: expulsion, which requires a two-thirds vote; or censure, which requires a majority vote. Censure is a formal statement of disapproval. While censure (sometimes referred to as condemnation or denouncement) is less severe than expulsion in that it does not remove a senator from office, it is nevertheless a formal statement of disapproval that can have a powerful psychological effect on a member and on that member's relationships in the Senate.
