Senate Republican Conference

The Senate Republican Conference is the formal organization of the Republican senators in the United States Senate. 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. The Senate Republican Conference assists Republican senators by providing a full range of communications services including graphics, radio, television, and the Internet. Its chairman is Senator Tom Cotton, and its vice chairman is Senator James Lankford.

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.

The conference continued to meet in private to assure confidentiality and candor. This practice was suspended only once, on May 27, 1919, when the conference reaffirmed its commitment to the seniority system for choosing committee chairmen by electing Senator Boies Penrose of Pennsylvania as chairman of the finance committee over objections from Progressive Republican insurgents. (This was apparently the only open party conference in the history of the Senate.)

During this period, the chairman also served as informal floor leader. One reason for the lack of a formal post was that committee chairmen usually took responsibility to move to proceed to the consideration of measures reported by their respective committees and managed the legislation on the floor. The first recorded Conference election of a formal floor leader was held March 5, 1925, when the conference chairman, Senator Curtis of Kansas, was unanimously chosen to serve in both posts.

Throughout the 1920s, when Republicans held the Senate majority, the conference met chiefly at the beginning of each session to make committee assignments; for the remainder of the session, Members were notified of the order of business by mail. This slow pace continued through the 1930s, when Republican senators were so few that they dispensed with a permanent whip, and the conference chairman and floor leader, Senator Charles L. McNary of Oregon, appointed senators to serve as whip on particular pieces of legislation.

Senator McNary died in 1944, and the posts of conference chairman and floor leader were separated in 1945. Senator Arthur H. Vandenberg of Michigan became chairman and Senator Wallace H. White, Jr., of Maine became floor leader. This separation has continued to be one of the chief differences between the Republican and Democratic Conferences, since the floor leader of the Democrats has continued to serve as their conference chairman.
