One of the procedure for holding a person in contempt involves only the chamber concerned. Following a contempt citation, the person cited is arrested by the Sergeant-at-Arms for the House or Senate, brought to the floor of the chamber, held to answer charges by the presiding officer, and then subjected to punishment as the chamber may dictate (usually imprisonment for punishment, imprisonment for coercion, or release from the contempt citation).
