the members of a joint committee are drawn from
Joint Committee on Inaugural Ceremonies The members are sitting members of the United States Senate and House of Representatives. Typically, the House members include the Speaker of the House as well as the House majority and minority leaders. The Senate members are drawn from the leadership of the Senate Committee on Rules and Administration (previously known by other names). A senator acts as Chairman of the Joint Committee; the chairman is therefore drawn from the party in control of the Senate, which may or may not be the same party as the president-elect's. Membership in the committee gives its members the opportunity to control tickets to the inauguration ceremonies.
United States House of Representatives Speakers serve as chairs of their party's steering committee, which is responsible for assigning party members to other House committees. The Speaker chooses the chairmen of standing committees, appoints most of the members of the Rules Committee, appoints all members of conference committees, and determines which committees consider bills.
