The National Republican Senatorial Committee (NRSC) is the only national organization solely devoted to electing Republicans to the U.S. Senate. The NRSC provides invaluable support and assistance to current and prospective Republican U.S. Senate candidates in the areas of budget planning, election law compliance, fundraising, communications tools and messaging, research and strategy.
The National Republican Congressional Committee (NRCC) is the Republican Hill committee which works to elect Republicans to the United States House of Representatives.
The NRCC was formed in 1866, when the Republican caucuses of the House and Senate formed a "Congressional Committee". It supports the election of Republicans to the House through direct financial contributions to candidates and Republican Party organizations; technical and research assistance to Republican candidates and Party organizations; voter registration, education and turnout programs; and other Party-building activities.
