Jen Kerns offers Daily Caller readers a case for designating the Antifa group as a terrorist organization.

The Federal Bureau of Investigation defines domestic terrorism as violence perpetrated by groups with “extremist ideologies of a political, religious, social, racial, or environmental nature.”

Antifa meets that definition. The group consists of American citizens radicalized by left-wing ideology who carry out threats of violence. It’s high time to classify Antifa as a domestic terror organization.

Over the weekend, the group exploded in rage once again in Portland, Oregon. Antifa members injured several people, including an elderly man. Journalist Andy Ngo, who was covering the event, went to the hospital for a head injury and brain bleeding.

To date, federal officials have not classified Antifa a domestic terror group despite endless photographs, eyewitness accounts and video evidence supporting the designation.

During a protest of conservative speaker Ben Shapiro last year on the University of California’s Berkeley campus, Antifa members reportedly destroyed campus property, set fire to trash cans, beat up college Republicans and forced students to shelter in place. (Campus police stood by doing nothing.) The school settled the case, paying organizers nearly $100,000.

It’s difficult to understand why the group hasn’t received a terror designation.
