The United States Constitution specifically grants impeachment and conviction powers, respectively, to the House of Representatives and Senate. It also grants both congressional bodies the power to expel their own members, though it does not mention censure. Each body adopts rules allowing censure, which is "stronger than a simple rebuke, but not as strong as expulsion." In general, each house of Congress is responsible for invoking censure against its own members; censure against other government officials is not common. Because censure is not specifically mentioned as the accepted form of reprimand, many censure actions against members of Congress may be listed officially as rebuke, condemnation, or denouncement.
