UPDATE 7:19 p.m.: Portland Police revoke permit, declare riot as protesters clash downtown

A pair of dueling protests is scheduled in downtown Portland Saturday afternoon. The first is a rally in the name of "freedom and courage" organized by Joey Gibson, U.S. Senate candidate for Washington and leader of right-wing, Vancouver-based Patriot Prayer.

The other is a counter-demonstration from local anti-fascist groups they say is an effort to defend the city from a crew of outside agitators.

The Patriot Prayer demonstration begins at 4 p.m. at Terry Schrunk Plaza. Supporters and counter-protesters alike are expected to arrive at least an hour ahead of time, with a march through the streets of Portland planned after the rally.
