Enforcement of Congressional Rules of Conduct: A Historical Overview
Released: 2015-02-23T00:00:00

Summary:
The Constitution vests Congress with broad authority to discipline its Members. Only since 1967, however, have both houses established formal rules of conduct and disciplinary procedures whereby allegations of illegal or unethical conduct may be investigated and punished.
In 1964, the Senate established its first permanent ethics committee, the Select Committee on Standards and Conduct, which was renamed the Select Committee on Ethics in 1977. In 1967, the House first established a permanent ethics committee, the Committee on Standards of Official Conduct, which was renamed the Committee on Ethics in 2011. A year after being established, each chamber adopted rules of conduct. Previously, Congress had dealt case by case with misconduct and relied on election results as the ultimate arbiter in questions of wrongdoing.
In 2008, with the adoption of H.Res. 895, the House created the Office of Congressional Ethics (OCE) to review allegations of impropriety by Members, officers, and employees of the House and, when appropriate, to refer "findings of fact" to the Committee on Standards of Official Conduct. The OCE board of directors comprises six board members and two alternates. Current Members of the House, federal employees, and lobbyists are not eligible to serve on the board. The OCE was reauthorized at the beginning of the 113th Congress. The Senate has not established a comparable office.
This report describes the evolution of enforcement by Congress of its rules of conduct for the House and Senate and summarizes the disciplinary options available to the House Committee on Ethics and the Senate Select Committee on Ethics.

paragraphs: Congressional authority to discipline Members is found in Article I, Section 5, clause 2 of the Constitution, which provides that "Each House may determine the Rules of its Proceedings, punish its Members for disorderly Behaviour, and, with the Concurrence of two thirds, expel a Member." Through the years, disorderly behavior has been interpreted as improper conduct and included support of rebellion, disloyalty, corruption, and financial wrongdoing. Only since the 1960s has each chamber systematically undertaken self-discipline related to conduct.
This report examines the creation and evolution of the House and Senate ethics committees and the formalization of the House and Senate ethics processes. It also describes some of the recent changes, implemented or proposed, in congressional enforcement of rules of conduct. It does not deal with changes to federal or state criminal law or with criminal prosecutions of Members of Congress.
subsections: section_title: History of Congressional Ethics Enforcement
paragraphs: Prior to the 1960s, neither the House nor the Senate had a mechanism to consistently exercise disciplinary powers against Members. When allegations of misconduct were investigated, it was often by an ad hoc or select committee created for that purpose. In addition, allegations were sometimes considered by the whole House or Senate without prior committee action. During this time, publicity and reelection were considered the major forms of redress for allegedly unethical behavior in Congress.
subsections: section_title: Creating Ethics Codes of Conduct
paragraphs: Historically, Congress did not have a formal ethics process. "For nearly two centuries," former Senate historian Richard Baker observed, "a simple and informal code of behavior existed. Prevailing norms of general decency served as the chief determinants of proper legislative conduct." During that time, Congress chose "to deal, on a case-by-case basis, only with the most obvious acts of wrongdoing, those clearly 'inconsistent with the trust and duty of a member.'"
Perceptions of wrongdoing or conflicts of interest by Members of Congress have changed over time. What might be viewed today as blatant impropriety could have been an accepted norm or simply ignored years ago. For example, when Daniel Webster was chair of the Senate Finance Committee (1833-1837), he was also on the payroll of the Bank of the United States. Very few colleagues, however, criticized him for being a bank official or for his practice of going from the Senate to the Supreme Court, which was then housed in the Capitol, to argue cases in which he had a legislative or financial interest. According to Dr. Baker, Webster made no effort to keep his business ties a secret. 
Not until the 1940s were concerns raised over the lack of specific standards of conduct and requirements for financial disclosure for government officials, and about the potential impact outside income might have on Members' decision making and behavior. For example, in 1946, during the 79 th Congress (1945-1946), Senator Wayne Morse introduced S.Res. 306, to require Senators to disclose sources of outside income. His resolution, which was not adopted, was predicated on the idea that Members' behavior should be above suspicion and that the disclosure of income would dispel rumors of impropriety.
In 1951, criticism of congressional investigative procedures began to increase with some commentators claiming that Members were abdicating responsibility for their behavior by relying on voters to "punish" misbehavior. Voters, however, might not possess adequate knowledge of their Member's behavior and were often quick to "forgive" Members disciplined by the chamber in which they served.
The 85 th Congress (1957-1958) adopted a general Code of Ethics for Government Service covering officials and employees in the three branches of government. Initially proposed in 1951 by Representative Charles Bennett, the Code of Ethics was adopted following a House investigation of presidential chief of staff Sherman Adams, who was alleged to have received valuable gifts from an industrialist being investigated by the Federal Trade Commission. The standards included in the Code of Ethics for Government Service are still recognized as continuing ethical guidance in the House and Senate. They are, however, not legally binding because the code was adopted by congressional resolution, not by public law.
The existence of a "club spirit" and reliance on unwritten norms of conduct continued in Congress until the 1960s. In 1966, political scientist Robert Getz observed that "the combination of historical precedent, the fear of partisan motivations, and the requirement of functioning in an atmosphere of mutual respect and cooperation has given rise to the view that Congress is not the forum before which the membership should be disciplined."
In the 1960s, investigations of alleged misconduct by Bobby Baker, secretary to the Senate majority, and Representative Adam Clayton Powell drew attention to the lack of specific congressional standards of conduct and a means of enforcing congressional self-discipline. Subsequently, the Senate created the Select Committee on Standards and Conduct in 1964, and the House established the Committee on Standards of Official Conduct in 1967. Each committee was given the authority to investigate allegations of wrongdoing by Members, officers, and employees; to adjudicate evidence of misconduct; to recommend penalties, when appropriate; and to provide advice on actions permissible under congressional rules and law.
section_title: Proposals for Extra-Congressional Ethics Enforcement
paragraphs: In seeking to be fair to Members, and not to prejudice the consideration of an allegation, the House and Senate ethics committees have operated quietly over the years. They often have been perceived, however, to be slow or reluctant to investigate and discipline colleagues and have been criticized on the basis of that perception. Subsequently, numerous proposals have been introduced in the Senate and the House to create an "independent" ethics organization. In the 110 th Congress (2007-2009), the House, for the first time, created the Office of Congressional Ethics, an independent ethics review body. The Senate has not established a comparable office.
During the 82 nd Congress (1951-1953), Senator J. William Fulbright introduced S.Con.Res. 21 to create an ethics commission of private citizens appointed by the Speaker of the House and the President pro tempore of the Senate. While not adopted by the Senate, S.Con.Res. 21 was favorably reported by a subcommittee of the Senate Labor and Human Resources Committee. In addition, the subcommittee, chaired by Senator Paul Douglas, recommended government-wide ethics changes including financial disclosure, restrictions on lobbying by former Members of Congress, regulation of campaign costs, restrictions on honoraria, and guidelines for representing constituent concerns before executive agencies.
In the 96 th Congress (1979-1981), Senator William Roth introduced S.J.Res. 144 to "establish an Independent Investigating Commission on Ethics to conduct investigations of allegations of improper conduct by Members of Congress arising out of the FBI investigation known as 'ABSCAM.'" The commission would have
establish[ed] a five-person independent commission of senior statesman to assist the Ethics Committees in both the Senate and the House by conducting investigations and making reports concerning the serious allegations of wrongdoing that have been made. These senior statesmen would have [had] the right to independently receive complaints and initiate investigations only of those matters directly related to the FBI investigation known as "ABSCAM." The Ethics Committees, would [have] retained the right to review any findings and to recommend any appropriate action to the full Senate and House.
S.J.Res. 144 was referred to the Committee on Governmental Affairs and did not receive further consideration.
The next discussion of a non-congressional ethics entity occurred during the 103 rd Congress (1993-1994), when the Joint Committee on the Organization of Congress held hearings on the congressional ethics process. Sitting and former Members of Congress, as well as congressional scholars, discussed the pros and cons of entities outside Congress assisting the ethics committees in the enforcement of congressional rules of conduct. Subsequently, the House Members on the committee recommended that "the Committee on Standards of Official Conduct should be authorized to use, on a discretionary basis, a panel of non-Members in ethics cases." No further action was taken.
During the 105 th Congress (1997-1998), the House Ethics Reform Task Force, co-chaired by Representatives Robert Livingston and Benjamin Cardin, considered the use of "distinguished private citizens" (including former Members of the House and judges) in the ethics process. Some witnesses before the task force had suggested the participation of "outsiders" would enhance public trust and confidence and minimize partisanship. Task force members, however, feared that the use of private citizens would interfere with the constitutional responsibility of each House to discipline its Members. A majority of the task force also believed that incumbent House Members better understand the practices of the House, and that Members accused of misconduct should be judged by their peers.
Accordingly, the task force recommended, and the House adopted, a policy of appointing a bipartisan reserve "pool" of House Members to serve on any House Committee on Ethics investigative subcommittees if needed. This is still the practice in the House.
There was a high level of interest in an independent ethics authority in the 109 th Congress (2005-2006) when numerous bills were introduced. Nonetheless, in March 2006, the Senate Committee on Homeland Security and Governmental Affairs voted against a proposal to establish an independent office to enforce congressional ethics and lobbying laws. Subsequently, the Senate defeated a similar amendment to a pending gift and lobbying reform measure ( S. 2349 ).
In the 110 th Congress, on January 18, 2007, during consideration of the Legislative Transparency and Accountability Act of 2007 ( S. 1 ), the Senate again rejected an amendment to establish a Senate Office of Public Integrity.
Outside enforcement of conduct or anti-corruption provisions against Members of the House and Senate is potentially complicated by Article I, Section 6, clause 1 of the Constitution, which provides Member protection from prosecution and questioning by outside law enforcement for certain official, legislative conduct. The Constitution states, "for any Speech or Debate in either House, they [Senators and Representatives] shall not be questioned in any other place." The Constitution's "Speech or Debate" clause may provide a practical necessity for internal congressional investigations and punishment of Members who violate chamber rules, federal law, or state law.
section_title: House of Representatives
paragraphs: Since the creation of the Committee on Ethics, the House of Representatives has amended the ethics review process to include both internal and external entities. The Committee on Ethics was initially created in 1967, as the Committee on Standards of Official Conduct, with the adoption of H.Res. 418. It continues to serve as the internal ethics committee. In 2008, the House created the Office of Congressional Ethics (OCE) to serve as an external review body for ethics complaints against Members, officers, and employees of the House. The relationship between the Committee on Ethics and the OCE is established in House and committee rules.
subsections: section_title: House Committee on Ethics
paragraphs: In the 114 th Congress, the Committee on Ethics is comprised of 10 Members, five from each party. A substantial part of the committee's work is advisory and is performed by its Office of Advice and Education, which provides information and guidance to House Members, officers, and employees on House rules and standards of conduct applicable to their official capacities. The committee provides training for House staff, reviews privately sponsored travel, and evaluates and certifies all public financial disclosure reports filed by Members, candidates for the House, and senior House staff.
The remaining committee work comprises investigations of Members, officers, and employees of the House and adjudication of cases against Members. The committee's investigative and adjudicative functions are found in House Rule X, clause 5(a)(4)(A) and (B); Rule XI, clause 3; and the Ethics Reform Act of 1989. 
subsections: section_title: Investigation
paragraphs: Complaints alleging misconduct or House rules violations by House Members or staff can only be filed with the Committee on Ethics by a Member of the House. Alternately, complaints can be filed by a person who is not a Member, but must be accompanied by written certification by a Member that the information is "submitted in good faith and warrants the review and consideration of the committee." Prior to 1997, members of the public (under certain conditions) as well as Members of the House could file a complaint against a Member, officer, or employee of the House. In September 1997, the House amended the rule to prohibit complaints filed by non-Members.
In the 110 th Congress, the Office of Congressional Ethics (OCE) was established to collect information from non-Members on potential misconduct and House rules violations by Members, officers, and staff. Following receipt of information, the OCE reviews the allegations and transmits relevant "findings" to the Committee on Standards for further scrutiny, when warranted. For more information on the OCE see the " Office of Congressional Ethics " section below. 
section_title: Adjudication
paragraphs: If the Committee on Ethics determines that an investigation is necessary, because of a Member complaint, an OCE referral, or direct House action, an ad-hoc investigative subcommittee is formed. Additionally, the Committee on Ethics may also initiate an investigation on its own. If a subcommittee is formed, the subcommittee is either populated by a group of Members, designated by the Speaker and the minority leader at the beginning of each Congress, who do not serve on the Committee on Ethics; by members of the Committee on Ethics; or both.
If the subcommittee finds that a violation of the House rules has occurred and transmits a Statement of Alleged Violations (formal charges) to the chair and ranking Member of the Committee on Ethics, the committee chair is then required to appoint an ad-hoc adjudicative subcommittee. The members of the adjudicative subcommittee are those members of the Committee on Ethics who were not members of the investigative subcommittee together with the chair and ranking Member of the committee. The subcommittee judges the evidence in the Statement of Alleged Violations and recommends sanctions, if the subcommittee concludes they are warranted.
In November 2010, in her opening remarks of an adjudicatory subcommittee hearing, then-chair of the Committee on Standards, Representative Zoe Lofgren, explained the adjudicatory process.
The role of an Adjudicatory Subcommittee is to determine, at a hearing, whether any count of the Statement of Alleged Violation has been proved by clear and convincing evidence. The purpose of this adjudicatory hearing is to do just that. However, it is important to bear in mind that this proceeding is a hearing, not a trial.
Attorneys from the Committee's non-partisan, professional staff are the moving party in these proceedings. Their role is to make a case for the Statement of Alleged Violation adopted by the Investigative Subcommittee.
At the adjudicatory hearing, the burden of proof rests with the Committee counsel to establish the facts alleged in each count of the Statement of Alleged Violation by clear and convincing evidence.
[The respondent] will have an opportunity to present his side of the story, should he wish to do so. A respondent is not required to present a case in his defense, and should [the respondent] chose not to present a case, the Subcommittee will not and may not draw a negative inference from that fact.
As members of the Adjudicatory Subcommittee, we are neither accusers nor are we defenders of our colleague…. Our job is to act impartially as finders of fact and law. We are honor bound to do so without regard to partisanship or bias of any sort. We are required to act honestly and fairly based on the evidence presented to us during the adjudicatory hearing.
Following a subcommittee investigation, the committee has historically recommended several punishments. These have included expulsion, censure, reprimand, and "Letters of Reproval" and "Letters of Admonition." Prior to the completion of House action, some 25 Members have left the House after court convictions, after inquiries were initiated, or after charges were brought by the committee. Departure from the House ends a case because the committee does not have jurisdiction over former Members.
The committee's first publicly announced action was in 1968 at the request of Speaker John McCormack. This was an inquiry into roll-call voting irregularities that resulted in some Members who were out of town being recorded as having voted. The committee concluded that the problem was not deliberate and was the result of an overworked tally clerk, and urged the House to install a modernized system of voting.
section_title: Recent Major Procedural Changes
paragraphs: The House has made a number of changes to the ethics process and the Committee on Ethics in the past several Congresses. This section briefly discusses these changes and their effect on the enforcement of the House's rules of conduct.
subsections: section_title: 105th Congress
paragraphs: In February 1997, the House established the 10-member bipartisan Ethics Reform Task Force to review the existing House ethics process and recommend reforms. Co-chaired by Representatives Robert Livingston and Benjamin Cardin, the task force held hearings and issued a report that recommended a series of changes to strengthen the committee and ensure that all Members, officers, and employees were treated equitably. On September 18, 1997, the House adopted H.Res. 168 , incorporating the recommendations of the Ethics Reform Task Force. The new adopted rules
changed the way individuals who are not Members of the House file complaints with the committee by requiring them to have a Member certify in writing that the information was submitted in good faith and warrants consideration by the Committee on Standards of Official Conduct; decreased the size of the committee to 10 members from 14; established a 20-person pool of Members (10 from each party) to participate in the work of the committee as potential appointees to any investigative subcommittee that the committee might establish; required the chair and ranking minority Member of the committee to determine within 14 calendar days or five legislative days, whichever comes first, if the information offered as a complaint meets the committee's requirements; allowed an affirmative vote of two-thirds of the members of the committee or approval of the full House to refer evidence of violations of law disclosed in a committee investigation to the appropriate state or federal law enforcement authorities; provided for a nonpartisan, professional committee staff; and allowed the ranking minority Member on the committee to place matters on the committee's agenda.
section_title: 109th Congress
paragraphs: In the 109 th Congress (2005-2006), the House rules adopted on January 4, 2005, included several new provisions affecting investigative procedures of the Committee on Ethics. The changes required the committee to notify any Member, officer, or employee whose conduct was referenced in a complaint against another Member, officer, or employee. In addition, unless the chair or ranking Member placed a complaint on the committee's agenda within 45 days of receipt, the committee was no longer required to act on such complaint. The new provisions, however, were rescinded and the former ones reinstated on April 27, 2005.
section_title: 110th Congress
paragraphs: During the 110 th Congress (2007-2008), the House passed H.Res. 451 , which required the Committee on Ethics to act within 30 days after a Member of the House is indicted or otherwise formally charged with criminal conduct in a U.S. court. If the committee does not empanel an investigative subcommittee to review the allegations, it must submit a report to the House describing why it has not done so and detailing what actions, if any, it has taken in response to the allegations. The provisions of H.Res. 451 were included in the rules adopted by the House for the 111 th Congress.
section_title: 111th Congress
paragraphs: In the first session of the 111 th Congress (2009-2011), the Committee on Ethics formed a bipartisan working group to help incorporate into the committee's rules the creation of the Office of Congressional Ethics (OCE). The group's recommended revisions were adopted by the committee on June 9, 2009, and cover the committee's role vis-à-vis an OCE review of allegations against a Member, officer, or employee and when a matter has been referred to the committee from the OCE.
section_title: 113th Congress
paragraphs: At the beginning of the 113 th Congress (2013-2014), the House amended the process for releasing an Office of Congressional Ethics report to the Committee on Ethics and made modifications to the Code of Conduct to clarify the hiring of relatives of Members and employees, retention of oaths (or affirmations) by the Clerk of the House and the Sergeant at Arms, and the use of official funds for personal and charter aircraft, when it adopted the rules for the 113 th Congress ( H.Res. 5 ).
section_title: 114th Congress
paragraphs: As part of the rules package for the 114 th Congress (2015-2016), the House amended House Rule XI, clause 3 to prohibit the Ethics Committee from taking "any action that would deny any person any right or protection provided under the Constitution of the United States." Additionally, Rule XI, clause 3(a)(6)(B)(i) was amended to require mandatory ethics training for new Members, Delegates, Resident Commissioners, officers or employees. Previously, only new officers or employees were required to undergo mandatory ethics training.
section_title: Office of Congressional Ethics
paragraphs: On January 31, 2007, to address criticisms leveled against the closed nature of the Committee on Ethics, then-House Speaker Nancy Pelosi and then-Minority Leader John Boehner, announced the creation of the Special Task Force on Ethics Enforcement in the House of Representatives. Chaired by Representative Michael Capuano, the task force was charged with considering "whether the House should create an outside enforcement entity, based on examples in state legislatures and private entities."
On December 19, 2007, Chairman Capuano released a report on behalf of several task force members and introduced H.Res. 895 to create an office of congressional ethics, composed of six board members jointly appointed by House leaders. On March 3, 2008, Chairman Capuano released proposed amendments to H.Res. 895 and on March 11, the House adopted H.Res. 895 . The first OCE board members were appointed in July 2008. The OCE has been reauthorized by the House as part of the rules package in subsequent Congresses. 
The relationship between the OCE and the Committee on Standards continues to evolve. Regardless of the balance between the OCE and the Committee on Standards, OCE only has jurisdiction over House Members, officers, and employees. To date, the Senate does not have a comparable entity.
section_title: Senate
paragraphs: Initially created in 1964, the Senate Committee on Standards and Conduct was renamed the Select Committee on Ethics in 1977. Like its House counterpart, the Senate Select Committee on Ethics is bipartisan and in the 114 th Congress consists of six members, three from each party. It has both a disciplinary and advisory function. Unlike the House committee, the Senate Ethics Committee does not separate its investigative and adjudicatory functions, and it has no "statute of limitations" for investigations of alleged past violations.
subsections: section_title: Investigations and Adjudication
paragraphs: In the Senate, no restrictions exist on who can file a complaint or allegation with the committee. Once a sworn complaint has been received or if the committee initiates an inquiry into possible wrongdoing by a Senator, Senate officer, or Senate employee, committee rules establish a multi-stage review and adjudication process. The committee first begins a preliminary inquiry. If there is substantial evidence of a violation, charges are brought, and the committee begins an adjudicative process to determine the merits of the charges and appropriate sanctions.
As a consequence of committee action, Senators have been expelled and censured, for their behavior. In addition, at least two Senators resigned prior to expected expulsion and multiple Senators have been admonished by the Select Committee for their actions.
section_title: Recent Major Procedural Changes
paragraphs: In 1993, the Senate established the bipartisan Senate Ethics Study Commission to study the procedures of the Select Committee on Ethics. In March 1994, the commission issued its final report and recommendations. The recommendations languished, however, until the Senate adopted S.Res. 222 on November 5, 1999. S.Res. 222 streamlined the Senate's ethics enforcement process and required the committee to educate Members, officers, and employees about the laws, rules, and regulations applicable in their official duties. The major provisions of S.Res. 222 provided for the following:
The previous multi-stage process of an "initial review" before a "preliminary inquiry" was replaced by a single-phase "preliminary inquiry." Under this procedure, if there is substantial evidence of a violation, charges are issued and an "adjudicative review" is conducted to determine the merits of charges and appropriate punishment. This phase may include a hearing. The changes did not affect the ability of outside groups to file allegations against a Member, officer, or employee of the Senate. A uniform set of potential sanctions were established for rules violations that are to be used alone or in combination. These sanctions include financial restitution, referral to a party conference (regarding seniority or positions of responsibility), censure, and expulsion. The Ethics Committee retained the flexibility to propose other penalties and was authorized to issue a reprimand to an individual without his or her consent (as had been required previously) after the opportunity for a hearing and with the right of appeal to the Senate. Also, public or private "Letters of Admonition" can be issued by the Ethics Committee. These letters, which previously had been used by the committee, are not considered a form of discipline.
The reforms added financial restitution to the possible sanctions (in addition to suspension and dismissal) that might be made against a Senate officer or employee.
section_title: Conclusion
paragraphs: Since the creation of the House and Senate ethics committees, entities both inside and outside of Congress have periodically evaluated the committees' work. These evaluations have resulted in an episodic debate over whether Members of Congress are doing a good job in following the mandate of the Constitution for self-discipline.
Inevitably, congressional ethics enforcement is often linked to appearances of impropriety by Members and changing perceptions on "conflict of interest." Often the perception of wrongdoing or a conflict of interest is all that is needed for an investigation. Ethicist Michael Josephson summarized the importance of the perception of wrongdoing.
The core concept of this ... ethical consciousness is the demand that public servants perceive and avoid both actual and apparent wrongdoing ... it is no defense that an act is legal or that there is no actual impropriety. It is enough that the conduct creates an inference of wrongdoing in the mind of a reasonable observer. More than ever, the public demands that its elected officials avoid both actual and apparent wrongdoing.
Evaluations often coincide with or follow periods when numerous or notorious ethics questions involving Members arise. Following these periods, Members, experts, and the public often seek to redefine standards and create new enforcement mechanisms. Sometimes the House or Senate or both chambers act; on other occasions, no action is taken, or there is prolonged discussion or delay. Since the 1960s, however, Congress has developed more elaborate ethical standards and more structured means of self-discipline. "While more standards of conduct for all government officials have been enacted to increase public confidence, each new law creates a new offense."
