Federal investigators say they have arrested several alleged members of extremist and white supremacist groups who participated in the Jan. 6 riot at the U.S. Capitol building, including multiple participants in an alleged conspiracy.
People allegedly affiliated with organizations such as The Three Percenters, The Oath Keepers, Proud Boys, Texas Freedom Force, and other self-described Nazis and white supremacists were among the mob that stormed the U.S. Capitol building, according to federal investigators.
