The case, one of the largest filed by the justice ministry, is set to begin next month, but prosecutors have called for the trial to be delayed because they could add additional defendants to the indictment. Prosecutors told a federal judge in March that they were continuing to investigate the Proud Boys and that they believed they had found information to support additional charges. Others could be charged in the conspiracy case in the coming weeks, the justice ministry said. According to the indictment, Tarrio helped set up a management structure within the Proud Boys before January 6th. The text and signal messages on the indictment indicate that Tarrio was preparing for a “revolution” and that he was looking at documents that set out to occupy some “critical buildings” in Washington, including the Office of the Secretary-General and the Senate. Tarrio was not in Washington on the day of the attack. He was arrested on Jan. 4 for bringing large-capacity rifle cartridges to DC and ordered him to leave the city. Prosecutors say that before Tarrio left, he allegedly met with Oath Keeper chief Stewart Rhodes in a garage in Washington. The two met for about 30 minutes, according to the indictment, and at least one participant “mentioned the Capitol.” Tarrio then traveled to Baltimore, prosecutors say, where he helped instruct and encourage other Proud Boys as they invaded the Capitol.
