President Donald Trump’s administration has sued Los Angeles, claiming the city is obstructing the enforcement of federal immigration laws and creating a lawless environment.

The Trump administration has filed a lawsuit against the city of Los Angeles over its immigration policies, the Justice Department announced Monday, claiming sanctuary policies limiting cooperation with federal immigration authorities clash with federal law.

The Trump Administration is suing Los Angeles over sanctuary city policies that limit the city’s cooperation with federal immigration enforcement, claiming that they led to “lawlessness” when thousands of people took to the streets earlier this month to protest the President’s mass-deportation operation.
