No rights or privileges are forfeited under the Constitution, statutory law, or the Rules of the Senate merely upon an indictment for an offense. Internal party rules in the Senate may be relevant, however, and the Senate Republican Conference Rules, for example, have required an indicted chairman or ranking Member of a Senate committee, or a member of the Senate party leadership, to temporarily step aside from his or her leadership or chairmanship position, although the Member's service in Congress would otherwise continue. It should be noted that Members of Congress do not automatically forfeit their offices even upon conviction of a crime that constitutes a felony. There is no express constitutional disability or "disqualification" from Congress for the conviction of a crime, other than under the Fourteenth Amendment for certain treasonous conduct after having taken an oath of office. Under party rules, however, Members may lose their chairmanships of committees or ranking Member status upon conviction of a felony, and this has been expressly provided under the Senate Republican Conference Rules. Conviction of certain crimes may subject Senators to internal legislative disciplinary proceedings, including resolutions of censure, as well as expulsion from the Senate upon approval of two-thirds of the Members. An attempt to mandatorily suspend an indicted or convicted Member from voting or participating in congressional proceedings raises several issues. Although the Supreme Court has not needed to address the subject of recall of Members of Congress directly, other Supreme Court decisions, as well as other judicial and administrative rulings, decisions, and opinions, indicate that (1) the right to remove a Member of Congress before the expiration of his or her constitutionally established term of office resides exclusively in each house of Congress as established in the expulsion clause of the United States Constitution and (2) the length and number of the terms of office for federal officials, established and agreed upon by the states in the Constitution creating that federal government, may not be unilaterally changed by an individual state, such as through the enactment of a recall provision or other provision limiting, changing, or cutting short the term of a United States Senator or Representative. Salary

No law or Rule exists providing that a Member of the Senate who is indicted for or convicted of a crime must forfeit his or her congressional salary. The states may not, therefore, by statute or otherwise, bar from the ballot a candidate for federal office because such person is indicted or has been convicted of a felony. However, the federal pensions of Members of Congress will be affected in two general instances: upon the conviction of a crime concerning any of the national security offenses listed in the so-called "Hiss Act," and upon the conviction of any one of several felony offenses relating to public corruption, abuse of one's official position in the Congress, fraud, or campaign finance laws if the elements of the offense relate to the official duties of the Member.
There are no federal statutes or Rules of the Senate that directly affect the status of a Senator who has been indicted for a crime that constitutes a felony. No rights or privileges are forfeited under the Constitution, statutory law, nor the Rules of the Senate upon an indictment. Under the Rules of the Senate, therefore, an indicted Senator may continue to participate in congressional proceedings and considerations. Under the United States Constitution, a person under indictment is not disqualified from being a Member of or a candidate for reelection to Congress. Internal party rules in the Senate may, however, provide for certain steps to be taken by an indicted Senator. For example, the Senate Republican Conference Rules require an indicted chairman or ranking Member of a Senate committee, or a member of the party leadership, to temporarily step aside from his or her leadership or chairmanship position.
Members of Congress do not automatically forfeit their offices upon conviction of a crime that constitutes a felony. No express constitutional disability or "disqualification" from Congress exists for the conviction of a crime, other than under the Fourteenth Amendment for certain treasonous conduct by someone who has taken an oath of office to support the Constitution. Unlike Members of the House, Senators are not instructed by internal Senate Rules to refrain from voting in committee or on the Senate floor once they have been convicted of a crime which carries a particular punishment. Internal party rules in the Senate may affect a Senator's position in committees. Under the Senate Republican Conference Rules, for example, Senators lose their chairmanships of committees or ranking Member status upon conviction of a felony.
Conviction of certain crimes may subject—and has subjected in the past—Senators to internal legislative disciplinary proceedings, including resolutions of censure, as well as an expulsion from the Senate upon approval of two-thirds of the Members. Conviction of certain crimes relating to national security offenses would result in the Member's forfeiture of his or her entire federal pension annuity under the provisions of the so-called "Hiss Act" and, under more recent provisions of law, conviction of a number of crimes by Members relating to public corruption, fraud, or campaign finance law will result in the loss of the Member's entire "creditable service" as a Member for purposes of calculating his or her federal retirement annuities if the conduct underlying the conviction related to one's official duties.
