AdTarrio hasn't been charged in connection with the riots, but the latest indictment refers to him by his title as Proud Boys' chairman.
Nordean, 30, of Auburn, Washington, was a Proud Boys chapter president and member of the group’s national “Elders Council.” Biggs, 37, of Ormond Beach, Florida, is a self-described Proud Boys organizer.
Proud Boys members, who describe themselves as a politically incorrect men’s club for “Western chauvinists,” have frequently engaged in street fights with antifascist activists at rallies and protests.
Vice Media co-founder Gavin McInnes, who founded the Proud Boys in 2016, sued the Southern Poverty Law Center for labeling it as a hate group.
Several Proud Boys also entered the Capitol building itself after the mob smashed windows and forced open doors.
