The complaint targets the so-called "sanctuary city" ordinance, alleging it hampers the crackdown on a "crisis of illegal immigration."

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 Department of Justice alleges that Los Angeles' sanctuary city policies interfere with the federal government's ability to enforce immigration laws.
