(Portland, OR)  --  Mayor Ted Wheeler is apologizing to peaceful protesters who were tear gassed by police during nightly demonstrations against police brutality in the city.  Wheeler spoke at a news conference yesterday, saying he agreed with community members that Portland Police Bureau officers did use tear gas indiscriminately during nights in May and June.  Wheeler says state troopers taking over the guarding of the federal courthouse from federal officers will be under the same restrictions as Portland Police, meaning they cannot use tear gas unless someone's life is in danger.
