• Activist John Earle Sullivan, who has often posed as a journalist to record protests, joined supporters of Donald Trump in the Jan. 6 riot at the U.S. Capitol and is charged with crimes for his participation. 

• Sullivan extensively recorded the riot and he can be heard in his footage cheering on the violent acts as he followed rioters through the Capitol.

  We found no evidence that he is a member of antifa, or that he caused the riot.
