President Trump’s Department of Justice is suing the city of Los Angeles on the grounds that its sanctuary city policy is an obstruction to the federal government’s mass deportation campaign.

President Donald Trump has federalized the National Guard and dispatched Marines to the city to respond to protests of ICE immigration raids. The ICE agents, many of whom are masked, have been spotted throughout the region, arresting about 2,000 immigrants since June 6, according to internal documents reviewed by The New York Times.

President Donald Trump's administration sued Los Angeles on Monday over policies limiting city cooperation with federal immigration authorities, continuing a confrontation over the Republican's deportation efforts in a largely Democratic city.
