Portland, Oregon is an Antifa-controlled city. The mayor is one of them in all but name, allowing them to run riot on targeted opposition and using the police only to perform a few token arrests that don't do any real damage to Antifa while denying the population the protection of the law that justifies their existence as an agency. If Hillary were in the White House, they would be running like this across the country and not just in Democrat-controlled cities.
Yesterday they targeted and assault journalist Andy Ngo, a gay Asian man, who was there to cover their protest. They threw milkshakes at him lined with quick-drying cement. He spent the night in the hospital due to bleeding on the brain, in addition to the bruising he sustained, and it is no surprise that their fellow travelers in the media covered for them by justfying the violence as "defense".
