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.
Chairman of the Joint Chiefs of Staff The Chairman of the Joint Chiefs of Staff (CJCS) is, by U.S. law, the highest-ranking and senior-most military officer in the United States Armed Forces[2] and is the principal military advisor to the President, the National Security Council,[3] the Homeland Security Council,[3] and the Secretary of Defense.[3][4] While the Chairman of the Joint Chiefs of Staff outranks all other commissioned officers, he is prohibited by law from having operational command authority over the armed forces; however, the Chairman does assist the President and the Secretary of Defense in exercising their command functions.[2]
