As members of the Proud Boys arrived at the foot of the U.S. Capitol on Jan. 6, they gathered as a unified front, donning bright orange beanies and tactical gear and carrying flags and megaphones used to lead chants that rippled through the roiling crowd.

Members of the all-male far-right group, which has a history of violence, posed for photos, displaying the “okay” hand gesture, which has become a “white power” sign, and moved through the crowd together.
