when they arise.16 When making recommendations to fill vacancies, conference rules specify that Steering and Outreach makes decisions independent of committee leadership. Ultimately, all recommendations made by Steering and Outreach are subject to approval by the full conference. In considering committee assignments, the Steering Committee is directed by Conference Rule X, clause 3, to make recommendations “giving due consideration” to seniority of service in the Senate, the preferences of Democratic Senators, and uninterrupted service on the committee(s) in question.17 The Steering Committee is also directed to assign freshman members of the conference to at least one “A” committee (including Intelligence) of their choice “to the extent possible.” The Democratic Conference also prioritizes the reappointment to committees (1) of Senators who lose an assignment because of changes in the ratio between the majority and minority parties (sometimes referred to as “bumping rights”) or (2) of Senators who voluntarily relinquish an assignment at the request of the Conference Chair. In either case, conference rules state that those Senators will receive priority in filling vacancies on committees where their assignments were lost. Limitations The Democratic Conference sets a number of limitations on how its members are assigned to committees. Certain committees are designated as exclusive (sometimes informally referred to as “Super A” committees), and Democratic Senators may not serve on more than one until all members of the conference are assigned to at least one. Per Conference Rule X, clause 9, the following committees are deemed exclusive: • Appropriations, • Armed Services, and • Finance. This limitation does not apply to Democratic Senators who were serving on more than one exclusive committee prior to the rule’s formal adoption by the conference in 2017. In addition, the Steering and Outreach Committee may waive this rule for other members of the conference as considered necessary. Democratic Senators from the same state may not be recommended to serve together on the same committee by the Steering and Outreach committee.18 This restriction can also be waived by Steering and Outreach as desired.

That is, if a Democratic Senator had prior Senate service, left Congress, and then was later reelected, their seniority would begin at the time of their reentry into the party conference. 18 Democratic Conference Rule X, clause 5. 19 The Republican Committee on Committees is appointed by the chair of the Republican Conference and then (continued...)

~~multi-step~~24 Democratic Conference Rules Democratic committee chairs (or ranking minority members) are primarily nominated by the Steering and Outreach Committee, subject to approval by the full Democratic Conference. Other nominations for these positions may be considered only if the candidate nominated by Steering and Outreach fails to be approved by a majority vote of the conference. When a committee leadership position has multiple candidates, the conference votes by secret ballot. If no candidate receives majority support, the candidate with the least votes is eliminated, and the conference proceeds to the next ballot. This process continues until a single candidate wins majority support (or fails to do so and new recommendations can be made). When there is only one candidate for a committee leadership post, they are still subject to vote by the conference and must receive majority support to be elected.25 Once candidates for committee leadership have been approved by the Democratic Conference, their names are submitted to the Senate in the form of a simple resolution for consideration and adoption by the chamber. 22 Rules and Precedents of the Senate Republican Conference, “Service re: Two Republican Senators from the Same State Serving on the Same Committee,” p. 6, and “Precedents in Selection from Minutes of the Republican Conference,” p. 8. 23 Senate Rule XXV, paragraph 4(e)(1). 24 For example, the chair of the Senate Committee on Finance could also concurrently serve as the chair of the Joint Committee on Taxation. 25 Democratic Conference Rule V describes the balloting procedures detailed in this paragraph. Congressional Research Service 7 Rules Governing Senate Committee and Subcommittee Assignment Procedures Limitations Democratic Conference rules are stricter than Senate rules on how many committee leadership positions an individual Senator can hold simultaneously. Democratic Senators may generally hold no more than a total of two committee leadership posts at the same time (either as chair/ranking of one committee and one subcommittee, or as chair/ranking on two subcommittees). Within the conference, this limitation is sometimes referred to as the “two gavel rule.” Holding a third gavel is permitted, if necessary, only after all members of the conference have been given the opportunity to obtain two gavels. Further limitations on holding committee leadership posts apply to the Democratic Leader and Democratic Whip. The Democratic Leader is prohibited from serving as a chair or ranking minority member on any standing committee (or subcommittee). The Democratic Whip may serve only as chair or ranking minority member for either one standing committee or one subcommittee. Republican Conference Rules In the Republican Conference, committee chairs (and ranking minority members) are subject to a multistep approval process, first by Republican committee members, then the full conference, approval process, first by Republican committee members, then the full conference,
and finally by formal approval of the committee membership appointment resolution (which and finally by formal approval of the committee membership appointment resolution (which

26 Republican Conference Rule V, Section B(2), specifies that “time served as ranking member shall not be counted as time served as chairman.” This means that, in the event of changes in party control of the Senate, a Senator could serve as chair and then ranking member for up to 12 cumulative years. For example, Senator John Doe could serve as committee chair for four years before the Republican Party then becomes the minority party in the Senate for the next six years. During those six years, Senator John Doe could serve as ranking minority member on the committee—none of which counts against his two remaining eligible years to be chair. After these six years as ranking member, the Republican Party could gain majority control of the Senate and Senator John Doe is eligible to serve two more years as committee chair before he is ineligible for further service as chair or ranking minority member.

Instead, the party’s rules emphasize limitations on leadership obtaining subcommittee gavels until after all members of the conference have an opportunity to secure one. By long-standing practice, the Democratic Conference has determined subcommittee chairs (or ranking minority members) by seniority on the full committee. Congressional Research Service 11 Rules Governing Senate Committee and Subcommittee Assignment Procedures Limitations Democratic Conference Rule XI provides that every Democratic Senator shall serve as chair (or ranking minority member) of at least one subcommittee and of no more than two (or of one standing committee and one subcommittee). As mentioned in the committees’ section, this concept in the Democratic Conference is sometimes referred to as the “two gavel rule.” Democratic Senators can hold a third gavel on a committee or subcommittee, as needed, after all other members of the conference have had the opportunity to hold two. Additional limitations apply to certain leadership positions within the Democratic Conference and for chairs (or ranking minority members) of “A” committees. Conference Rule XI prohibits the Democratic Leader from serving as chair/ranking for any standing committee or subcommittee. The Democratic Whip is permitted to serve as chair/ranking for only one standing committee or subcommittee. “A” committee chairs (or ranking minority members) cannot select a leadership spot on any subcommittee until all Democratic Senators have had the opportunity to choose one. .
