Evergreen State College has been under siege by left-wing protesters known as Antifa, forcing the Washington state school to move its graduation off campus.

The controversy started a month ago when a professor confronted students who were calling for a "day without white people" on the campus.

The interaction went viral and the professor, Bret Weinstein, later spoke out to Fox News' Tucker Carlson about being berated by the students.

"They imagined that I'm a racist," Weinstein said. "That has caused them to imagine that I have no right to speak."

Just days ago, Antifa "black bloc" activists clashed with a pro-Trump group which organized a free speech rally in Olympia and then walked to campus.

The rally's organizer said he was pepper-sprayed and left bloodied by the angry mob and some rally-goers found their vehicle tires slashed. 

On "Fox & Friends" today, Steve Doocy asked whether Antifa should be considered a domestic terrorist group. 

Author Scott Greer, who also works as deputy editor of Daily Caller, said it should be on the list because the group legitimizes and celebrates acts of violence against their opponents.

"They use terror tactics different from ISIS and other Islamic militant groups. Instead of bombs and guns, they use bricks and bike locks to intimidate and harass and suppress civil liberties and to threaten their political opponents," said Greer.

Greer said anyone Antifa disagrees with is labeled as a fascist, with the group claiming to fight broadly against fascism. 

"As you can tell, they have a very broad definition of 'fascist' if they're gonna target a progressive professor," he noted.

An Antifa protester was arrested in Pennsylvania last week for allegedly using a flagpole with a nail on top to stab a police horse. Other Antifa protesters were accused of using bike locks to attack opponents in Berkeley last month.
