(Portland, OR)  --  The Oregon National Guard is assisting police in Portland following a weekend of sometimes-violent protests that caused millions of dollars in damages.  Governor Kate Brown announced yesterday she would mobilize 50 unarmed guardsmen to the city to help law enforcement.  The move came in response to a request from Mayor Ted Wheeler to activate the National Guard to protect businesses.  Mayor Wheeler also extended the city curfew orders to resume at 8 p.m. last night until 6 a.m. today.
