Leadership of the United States House of Representatives includes: the speaker; majority and minority leaders; assistant leaders; whips; and a party caucus or conference.
The speaker acts as leader of the House and combines several institutional and administrative roles. Majority and minority leaders represent their respective parties on the House floor. Whips assist leadership in managing their party’s legislative program on the House floor. The majority party members and the minority party members meet in separate caucuses to select their leader.
Election of the speaker
The speaker of the House is elected at the beginning of a new Congress by a majority of the representatives-elect from candidates separately chosen by the majority and minority party as each holds an organizing caucus soon after the new Congress is elected. The speaker of the House is by law second in line to succeed the president, after the vice president.
