It's pretty funny that all the Republicans want the FBI to take on the "Terrorist Antifa Organization", and the FBI says they can't because there is no such thing. No Official Organization. No Big Cheese. No bank accounts, No funding. Alt-Right organization like Proud Boys and the KKK all have leaders because their philosophy attracts people who want to tell others what to do. Antifa is pretty much just individuals, doing what their name says. Anybody can go fight Fascism. No membership card needed! The only people creating Antifa are the Fascists themselves.
The last great organized Antifa movement was the Allied armed forces in the 1940's.
