Republican Conference of the United States Senate

The Senate Republican Conference is the formal organization of the Republican Senators in the United States Senate, who currently number 52. Over the last century, the mission of the Conference has expanded and been shaped as a means of informing the media of the opinions and activities of Senate Republicans. Today the Senate Republican Conference assists Republican Senators by providing a full range of communications services including graphics, radio, television, and the Internet. Its current Chairman is Senator John Thune, and its Vice Chairman is currently Senator Roy Blunt.

The Republican Conference of the United States Senate is a descendant of the early American party caucus that decided party policies, approved appointees, and selected candidates. The meetings were private, and early records of the deliberations do not exist. Senate Republicans began taking formal minutes only in 1911, and they began referring to their organization as the "conference" in 1913. An early outgrowth of the effort to enhance party unity was the creation, in 1874, of a Steering Committee to prepare a legislative schedule for consideration by the Conference. The Committee became a permanent part of the Republican organization.

The Steering Committee, formalized Republican "leadership" in the 19th century was minimal; most legislative guidance came from powerful committee chairmen managing particular bills. The Conference began to acquire significance, however, with the election of Senator William B. Allison of Iowa as Chairman in 1897, and during the terms of successors such as Senator Orville H. Platt of Connecticut and Senator Nelson W. Aldrich of Rhode Island. The Chairman in 1915, Senator Jacob H. Gallinger of New Hampshire, who two years earlier had elected a whip to maintain a quorum to conduct Senate business. Senator James W. Wadsworth, Jr. of New York was elected both conference secretary and whip; a week later the responsibilities were divided between Senator Wadsworth as Secretary and Senator Charles Curtis of Kansas, who was elected whip.
