The positions ofmajority leader andminority leader are held by twoUnited States senators and people of theparty leadership of the United States Senate. They serve as chief spokespersons for their respectivepolitical parties, holding the majority and the minority in the chamber. They are each elected to their posts by the senators of their partycaucuses: theSenate Democratic Caucus and theSenate Republican Conference.
By Senate precedent, thepresiding officer gives the majority leader priority in obtaining recognition to speak on the floor. The majority leader serves as the chief representative of their party in the Senate and is considered the most powerful member of the chamber. They also serve as the chief representative of their party in the entireCongress if theHouse of Representatives, and thus the office of thespeaker of the House, is controlled by the opposition party. The Senate's executive and legislative business is also managed and scheduled by the majority leader.
Theassistant majority leader andassistant minority leader of the United States Senate, commonly calledwhips, are the second-ranking members of each party's leadership. The main function of the majority and minority whips is to gather votes of their respective parties on major issues. As the second-ranking members of Senate leadership, if there is nofloor leader present, the whip may become acting floor leader.
The Senate of the119th Congress iscomposed in 2025 of 53Republicans, 45Democrats, and 2 independents; both the independentscaucus with the Democrats.
The leaders areSenatorsJohn Thune (R) ofSouth Dakota andChuck Schumer (D) ofNew York.[1] The assistant leaders, or whips, are SenatorsJohn Barrasso (R) ofWyoming andDick Durbin (D) ofIllinois.
At first aSenate leader was an informal position usually an influential committee chairman, or a person of great eloquence, seniority, or wealth, such asDaniel Webster and Nelson Aldrich. By at least 1850, parties in each chamber of Congress began naming chairs, and while conference and caucus chairs carried very little authority, the Senate party floor leader positions arose from the position of conference chair.[2]
Senate Democrats began electing their floor leaders in 1920 while they were in the minority.John W. Kern was a Democratic senator from Indiana. While the title was not official, the Senate website identifies Kern as the first Senate party leader, serving in that capacity from 1913 through 1917 (and in turn, the first Senate Democratic leader), while serving concurrently as chairman of the Senate Democratic Caucus.[3]
In 1925, the Republicans (who were in the majority at the time) also adopted this language whenCharles Curtis became the first (official) majority leader,[4] although his immediate predecessorHenry Cabot Lodge is considered the first (unofficial) Senate majority leader. However, despite this new, formal leadership structure, the Senate leader initially had virtually no power. Since the Democrats were fatally divided into northern liberal andsouthern conservative blocs, the Democratic leader had even less power than his title suggested.
Joseph T. Robinson of Arkansas, the Democratic leader from 1923 to 1937, saw it as his responsibility not to lead the Democrats, but to work the Senate for the president's benefit, no matter who the president was. When Coolidge and Hoover were president, he assisted them in passing Republican legislation. Robinson helped end government operation ofMuscle Shoals, helped pass theHoover Tariff, and stymied a Senate investigation of the Power Trust. Robinson switched his own position on a drought relief program for farmers when Hoover made a proposal for a more modest measure.Alben Barkley called Robinson's cave-in "the most humiliating spectacle that could be brought about in an intelligent legislative body." WhenFranklin Roosevelt became president, Robinson followed the new president as loyally as he had followed Coolidge and Hoover. Robinson passed bills in the Hundred Days so quickly thatWill Rogers joked "Congress doesn't pass legislation any more, they just wave at the bills as they go by.[5]
In 1937, the rule giving majority leader right of first recognition was created. With the addition of this rule, the Senate majority leader enjoyed far greater control over the agenda of which bills to be considered on the floor.
DuringLyndon B. Johnson's tenure as Senate leader, the leader gained new powers over committee assignments.[6]
TheUnited States Constitution designates thevice president of the United States as president of the Senate. The Constitution also calls for apresident pro tempore, to serve as the presiding officer when the president of the Senate (the vice president) is absent. In practice, neither the vice president nor the president pro tempore—customarily the most senior (longest-serving) senator in the majority party—actually presides over the Senate on a daily basis; that task is given to junior senators of the majority party. Since the vice president may be of a different party from the majority and is not a Senate member subject to discipline, the rules of procedure of the Senate give the vice president no power beyond the presiding role. For these reasons, it is the majority leader who, in practice, manages the Senate. This is in contrast to the House of Representatives, where the electedspeaker of the House has a great deal of discretionary power and generally presides over votes on legislative bills.[citation needed]
Under a long-standing Senate precedent, motions or amendments by the majority leader are granted precedence over other motions by other senators. The majority leader can therefore make at any time a motion to proceed to the consideration of a bill on the Senate Calendar (which contains almost exclusively bills which have been reported by the committee they were assigned to); a motion to proceed may be agreed to either byunanimous consent or through the invocation ofcloture. Conventionally, no senator other than the majority leader introduces motions to proceed, although every senator is theoretically allowed to. In addition, the majority leader can block consideration of amendments through a practice known as "filling the tree", and decides which members will fill each of the committee seats reserved to the majority party; members of committees are therefore often prone to following the instructions of the majority leader, and rarely place bills on the Senate Calendar without the latter's consent.[7]
The Democratic Party first selected a leader in 1920. The Republican Party first formally designated a leader in 1925.[8]
