The Congressional Western Caucus is a caucus within the United States House of Representatives composed of 62 members. Although it has historically been bipartisan, it is currently composed exclusively of Republicans. It was founded by then-representatives James V. Hansen (R-Utah), Bob Stump (R-Arizona), Joe Skeen (R-New Mexico) and Barbara Vucanovich (R-Nevada) in 1993 during the 103rd United States Congress. Despite its name, the Congressional Western Caucus has members from outside the Western United States, including as far east as Puerto Rico.
