Party leaders of the United States Senate

Existing floor leaders

The Senate of the 119th Congress is composed in 2025 of 53 Republicans, 45 Democrats, and 2 independents; both the independents caucus with the Democrats.

The leaders are Senators John Thune (R) of South Dakota and Chuck Schumer (D) of New York. The assistant leaders, or whips, are Senators John Barrasso (R) of Wyoming and Dick Durbin (D) of Illinois.

History

At first a Senate leader was an informal position usually an influential committee chairman, or a person of great eloquence, seniority, or wealth, such as Daniel 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.

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.

In 1925, the Republicans (who were in the majority at the time) also adopted this language when Charles Curtis became the first (official) majority leader, although his immediate predecessor Henry 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 and southern 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 of Muscle Shoals, helped pass the Hoover 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." When Franklin 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 that Will Rogers joked "Congress doesn't pass legislation any more, they just wave at the bills as they go by.

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.

During Lyndon B. Johnson's tenure as Senate leader, the leader gained new powers over committee assignments.

Senatorial role of the vice president

The United States Constitution designates the vice president of the United States as president of the Senate. The Constitution also calls for a president 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 elected speaker of the House has a great deal of discretionary power and generally presides over votes on legislative bills.

Powers of the majority leader

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 by unanimous consent or through the invocation of cloture. 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.

List of party leaders

The Democratic Party first selected a leader in 1920. The Republican Party first formally designated a leader in 1925.

Chief deputy whips

The chief deputy whip is the assistant to the majority/minority whip and the head of the whip operations team for their party. The current Republican (majority) chief deputy whip is Mike Crapo (Idaho), who's been holding the office since 2013 and the current Democratic (minority) chief deputy whip is Brian Schatz (Hawaii).
