Authorities arrested the leader of a right-wing group on the eve of a rally that's expected to draw people from around the U.S. to Portland, Oregon, on Saturday, prompting Patriot Prayer's Joey Gibson to urge his followers to "show up one hundred-fold" in response. Self-described anti-fascists have vowed to confront the right-wing groups at the downtown rally and the arrests of Gibson and five other right-wing supporters appeared to be intended to send a signal from police to organizers to remain peaceful or stay away. In a video he livestreamed on Facebook, Gibson accused the police of playing politics by arresting him and other right-wing members but not the masked demonstrators who beat up conservative blogger Andy Ngo at a June 29 rally.
