On Jan. 13, federal prosecutors unveiled their most ambitious charge to date in the ongoing investigations into the Jan. 6, 2021, insurrection: seditious conspiracy. The subjects of this charge are Stewart Rhodes and 10 alleged members of his far-right anti-government organization the Oath Keepers. Captured on video marching up the U.S. Capitol steps in “stack” formation, Rhodes’ organization became arguably the most visible face of the violent siege. Now its members are accused by the U.S. government of conspiring to “oppose the lawful transfer of presidential power by force.” (Rhodes’ lawyer has denied any wrongdoing.)
