(Salem, OR)  --  Oregon is one of 15 states and the District of Columbia that are suing President Trump.  The lawsuit announced yesterday stems from Trump's decision to end the Deferred Action for Childhood Arrivals program.  Oregon Attorney General Ellen Rosenblum had warned of the impending legal action yesterday at a rally in Portland.  DACA allowed those who were brought to the U.S. illegally as children to work and go to school without fear of deportation.
