EXCLUSIVE: A Secret Service counter sniper sent an email Monday night to the entire Uniformed Division (not agents) saying he will not stop speaking out until "5 high-level supervisors (1 down) are either fired or removed from their current positions." The counter sniper also said the agency "SHOULD expect another assassination attempt" before November and complained that he is no longer proud to be a USSS counter sniper after leadership failed the officers at the Trump rally in Butler on 7/13.
