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.
