College Republicans United, a student group that promotes anti-Jewish materials, also had a hand in organizing the event.

U.S. Rep. Andy Biggs over the weekend appeared at a rally that was co-sponsored by several extremist organizations, including the state’s chapter of the Proud Boys, and a student group that has promoted anti-Jewish materials.

Held in front of Arizona’s state Capitol, the 11th annual Second Amendment Rally featured not only a roster of gun rights advocates, but also several players from the state’s right-wing fringe.
