His “pressing charges” is wishful thinking on his part. No one is being arrested. No one is going to trial.
Mayor Bowser will have her police do a thorough investigation of Jack Posobiec to see if some charges can be found to press against him.
Posobiec was assaulted once before on camera by someone from antifa and that guy ended up serving time...he's been dealing with these DC punks for quite a while.
