The Second Amendment Caucus, also known as the House Second Amendment Caucus, is a congressional caucus consisting of conservative and libertarian Republican members of the United States House of Representatives who support Second Amendment rights. It was formed in 2016 to "promote a pro-gun agenda" according to founding chairman Thomas Massie.
The Second Amendment Caucus was originally established in 2004 by Representative Marilyn Musgrave (R-CO) and existed under that name until 2008. Representative Paul Broun (R-GA) recreated it in 2009 and titled it the Second Amendment Task Force. Thomas Massie reestablished it in December 2016 in light of the 2016 election results with 13 other congressmen.
