(Portland, OR)  --  Hundreds of protesters took to the streets of downtown Portland again last night to protest police brutality and systemic racism in law enforcement.  Protesters gathered at Revolution Hall and then marched across the Burnside Bridge.  The march ended at Pioneer Courthouse Square.  Protesters have been calling for change following the killing of George Floyd, a black man who died after a police officer knelt on his neck for nearly nine minutes in Minneapolis late last month.
