(Portland, OR)  --  TriMet officials are considering a suspension of service in downtown Portland this afternoon, in anticipation of a scheduled RISE UP protest of President-elect Trump's inauguration.  Organizers say more than ten-thousand people have RSVP'd on Facebook.  After initially saying it would suspend downtown service today, TriMet officials now say the agency is only preparing, or considering suspending service if protests get out of hand.  Mayor Ted Wheeler says he's told TriMet's general manager the city is well-prepared to protect riders and keep disruptions at a minimum.
