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.

The U.S. Department of Justice said on Monday it sued Los Angeles, California, over policies the city enacted shortly after President Donald Trump’s reelection to interfere with the federal government’s enforcement of its immigration laws.
