(Portland, OR) -- An eleventh-straight night of protests in Portland against the police-involved death of George Floyd in Minneapolis is in the books. Thousands of people gathered downtown for three separate protests. The largest demonstration drew thousands of people to the field near Revolution Hall, where protesters gathered for a rally before marching north. Several more protesters gathered at the Traffic Division building before marching onto the St. Johns Bridge. Police say both those protests were peaceful. Meanwhile, police say a third gathering near the Justice Center turned violent just before midnight, with agitators throwing bottles, hard-boiled eggs and other projectiles at officers. Police declared the gathering an unlawful assembly around midnight and arrested at least 20 people.
