The first Congress under the Constitution met on March 4, 1789, in the Federal Hall in New York City. The membership then consisted of 20 Senators and 59 Representatives. New York ratified the Constitution on July 26, 1788, but did not elect its Senators until July 15 and 16, 1789. North Carolina did not ratify the Constitution until November 21, 1789; Rhode Island ratified it on May 29, 1790. The Senate is composed of 100 Members, 2 from each State, who are elected to serve for a term of 6 years. Senators were originally chosen by the State legislatures. This procedure was changed by the 17th Amendment to the Constitution, adopted in 1913, which made the election of Senators a function of the people. There are three classes of Senators, and a new class is elected every 2 years. The House of Representatives comprises 435 Representatives. The number representing each State is determined by population, but every state is entitled to at least one Representative. Members are elected by the people for 2-year terms, all terms running for the same period. Both the Senators and the Representatives must be residents of the State from which they are chosen. In addition, a Senator must be at least 30 years of age and must have been a citizen of the United States for at least 9 years; a Representative must be at least 25 years of age and must have been a citizen for at least 7 years. [ How Much Do Members of Congress Really Make? ] A Resident Commissioner from Puerto Rico (elected for a 4-year term) and Delegates from American Samoa, the District of Columbia, Guam, and the Virgin Islands complete the composition of the Congress of the United States. Delegates are elected for a term of 2 years. The Resident Commissioner and Delegates may take part in the floor discussions but have no vote in the full House or in the Committee of the Whole House on the State of the Union. They do, however, vote in the committees to which they are assigned. Officers of CongressThe Vice President of the United States is the Presiding Officer of the Senate; in his absence the duties are taken over by a President pro tempore, elected by that body, or someone designated by him. The Presiding Officer of the House of Representatives, the Speaker of the House, is elected by the House; he may designate any Member of the House to act in his absence. The positions of Senate majority and minority leader have been in existence only since the early years of the 20th century. Leaders are elected at the beginning of each new Congress by a majority vote of the Senators in their political party. In cooperation with their party organizations, leaders are responsible for the design and achievement of a legislative program. This involves managing the flow of legislation, expediting noncontroversial measures, and keeping Members informed regarding proposed action on pending business. Each leader serves as an ex officio member of his party's policymaking and organizational bodies and is aided by an assistant floor leader (whip) and a party secretary. [ How to Write Effective Letters to Congress ] The House leadership is structured essentially the same as the Senate, with the Members in the political parties responsible for the election of their respective leader and whips. The Secretary of the Senate, elected by vote of the Senate, performs the duties of the Presiding Officer of the Senate in the absence of the Vice President and pending the election of a President pro tempore. The Secretary is the custodian of the seal of the Senate, draws requisitions on the Secretary of the Treasury for moneys appropriated for the compensation of Senators, officers, and employees, and for the contingent expenses of the Senate, and is empowered to administer oaths to any officer of the Senate and to any witness produced before it. The Secretary's executive duties include certification of extracts from the Journal of the Senate; the attestation of bills and joint, concurrent, and Senate resolutions; in impeachment trials, issuance, under the authority of the Presiding Officer, of all orders, mandates, writs, and precepts authorized by the Senate; and certification to the President of the United States of the advice and consent of the Senate to ratification of treaties and the names of persons confirmed or rejected upon the nomination of the President. The Sergeant at Arms of the Senate is elected by and serves as the Executive Officer of that body. He directs and supervises the various departments and facilities under his jurisdiction. He is also the Law Enforcement and Protocol Officer. As Law Enforcement Officer, he has statutory power to make arrests; to locate absentee Senators for a quorum; to enforce Senate rules and regulations as they pertain to the Senate Chamber, the Senate wing of the Capitol, and the Senate Office Buildings. He serves as a member of the Capitol Police Board and as its chairman each odd year; and, subject to the Presiding Officer, maintains order in the Senate Chamber. As Protocol Officer, he is responsible for many aspects of ceremonial functions, including the inauguration of the President of the United States; arranging funerals of Senators who die in office; escorting the President when he addresses a Joint Session of Congress or attends any function in the Senate; and escorting heads of state when they visit the Senate. The elected officers of the House of Representatives include the Clerk, the Sergeant at Arms, the Chief Administrative Officer, and the Chaplain. The Clerk is custodian of the seal of the House and administers the primary legislative activities of the House. These duties include: accepting the credentials of the Members-elect and calling the Members to order at the commencement of the first session of each Congress; keeping the Journal; taking all votes and certifying the passage of bills; and processing all legislation. Through various departments, the Clerk is also responsible for floor and committee reporting services; legislative information and reference services; the administration of House reports pursuant to House rules and certain legislation including the Ethics in Government Act and the Lobbying Disclosure Act of 1995; the distribution of House documents; and administration of the House Page Program. The Clerk is also charged with supervision of the offices vacated by Members due to death, resignation, or expulsion. Clerk of the HouseThe Sergeant at Arms maintains the order of the House under the direction of the Speaker and is the keeper of the Mace. As a member of the U.S. Capitol Police Board, the Sergeant at Arms is the chief law enforcement officer for the House and serves as Board Chairman each even year. The ceremonial and protocol duties parallel those of the Senate Sergeant at Arms and include arranging the inauguration of the President of the United States, Joint Sessions of Congress, visits to the House of heads of state, and funerals of Members of Congress. The Sergeant at Arms enforces the rules relating to the privileges of the Hall of the House, including admission to the galleries, oversees garage and parking security of the House, and distributes all House staff identification cards. Congressional CommitteesThe work of preparing and considering legislation is done largely by committees of both Houses of Congress. There are 16 standing committees in the Senate and 19 in the House of Representatives. The standing committees of the Senate and the House of Representatives can be viewed from the links below. In addition, there are select committees in each House (one in the House of Representatives), and various congressional commissions and joint committees composed of Members of both Houses. Each House may also appoint special investigating committees. The membership of the standing committees of each House is chosen by a vote of the entire body; members of other committees are appointed under the provisions of the measure establishing them. Each bill and resolution is usually referred to the appropriate committee, which may report a bill out in its original form, favorably or unfavorably, recommend amendments, report original measures, or allow the proposed legislation to die in committee without action.
