Senate Republican Conference
From OpenCongress Wiki
The Senate Republican Conference is the formal organization of the Republican members of the U.S. Senate.
History and Role
The Republican Conference is a descendant of the early American party caucuses 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. 
Today, the primary responsibility of the Senate Republican Conference is assisting Republican senators by providing a full range of communications services including graphics, radio, television, and internet. 
The Republican Conference chooses a chairperson at the outset of each Congress. Sen. Rick Santorum (R-Pa.) was chosen to lead the conference during the 109th Congress, while Sen. Kay Bailey Hutchison (R-Texas) was picked as the vice chair.
