The FBI has arrested John Sullivan in Utah on charges relating to his activities in and around the Capitol during the 6 January riot. According to the probable cause affidavit submitted by the FBI for the arrest warrant, Sullivan is the leader of an organization called Insurgence USA through which he organizes protests. (The Insurgence USA website appears to indicate the organization is loosely affiliated with Black Lives Matter.) The affidavit states that Sullivan admitted wearing a ballistic vest and carrying a gas mask during the riot.
The affidavit does not allege any connection between Sullivan’s actions and the President’s speech earlier in the day.
The case file on PACER has been sealed.
