(Portland, OR)  --  Portland is one of multiple cities across the country where demonstrations have been held to protest Donald Trump's win in the race for the White House.  The Police Bureau estimates that two-thousand people blocked Interstate 5 several times in marches on downtown Portland, which began around three o'clock yesterday afternoon.  Traffic snarls resulted after I-5 and I-84 were closed in both directions.  Police say demonstrators set fire to trash cans and spray-painted freeway dividers during the protests.
