(Portland, OR)  --  Dozens of people are facing charges after weekend protests over the police-involved murder of Minneapolis man George Floyd led to riots and looting in Portland.  Police arrested more than 50 people in Portland over the course of the weekend.  Mayor Ted Wheeler says authorities are still tallying the cost of the weekend's riots, but damage to Portland area businesses is being estimated at millions of dollars.  Wheeler says those who resorted to violence and looting did nothing to honor Floyd's life.  Cities across the country held protests over the weekend for Floyd, who died at the hands of police in Minneapolis while in custody last week.
