The U.S. Department of Justice on Thursday charged the leader of the far-right group Oath Keepers and 10 other members of the organization with seditious conspiracy related to the Jan. 6 attack on the U.S. Capitol, marking the first time the DOJ has used that charge in its Capitol riot investigation.

The indictment accuses Elmer Stewart Rhodes, the leader of the Oath Keepers, and his alleged co-conspirators, nine of whom have previously been charged in connection with the riot, of plotting to “oppose the lawful transfer of presidential power by force.”
