(Portland, OR) -- Portland's mayor is pushing back against the Trump administration's crackdown on sanctuary cities. Trump signed an executive order yesterday directing federal authorities to publish a list of sanctuary cities and empowering the Department of Justice to pursue action against cities that refuse to give up that status. In response, Mayor Keith Wilson said "Portland stands unwavering in its commitment to sanctuary policies." Meanwhile, the city's Police Chief Bob Day told KATU it's not the police department's role to participate in immigration enforcement. Oregon Governor Tina Kotek issued a statement promising not to comply with the Trump administration's immigration enforcement efforts as well.
