(Portland, OR)  --  Police say dueling rallies remained mostly peaceful in Portland over the weekend.  A Proud Boys rally that organizers said would draw thousands ended up drawing just hundreds in Portland on Saturday.  Hundreds of counter-protesters held their own rally about three miles away.  Later Saturday, protesters gathered across from the Portland Justice Center, where police say some demonstrators threw items at officers.  Governor Kate Brown praised law enforcement on Sunday for helping to prevent confrontations and violence.  The Multnomah County Sheriff's Office says officers made a total of 30 arrests during different gatherings on Saturday.
