A federal lawsuit accuses President Donald Trump’s administration of systematically targeting brown-skinned people in Southern California during an ongoing immigration crackdown that has put the region “under siege.

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

President Donald Trump escalated his war against sanctuary cities on Monday in a lawsuit blaming alleged "rioting, looting and vandalism" in Los Angeles on the city's policies.
