As rioters converged on the U.S. Capitol building, the grounds normally hailed as the seat of American democracy became a melting pot of extremist groups. Militia members, white supremacists, paramilitary organizations and fervent supporters of outgoing President Donald Trump stood shoulder to shoulder, unified in rage. Experts say years of increasing partisanship and a growing fascination of paramilitary groups combined with the coronavirus pandemic to create a conveyor belt of radicalization.
