These are the most aggressive charges brought by the Justice Department against the Proud Boys, and are the first allegations by prosecutors that the group tried to oppose by force the presidential transfer of power.

These developments come after Charles Donohoe, a Proud Boy from North Carolina, pleaded guilty in April and agreed to cooperate with the investigation. He was not named in Monday’s indictment.
The Justice Department has brought one other seditious conspiracy case against the leaders of the Oath Keepers, who are accused of extensively planning and preparing for violence on January 6.
