Justice Department suing California over sanctuary laws

Attorney General Jeff Sessions opened a new front in the legal war over California’s sanctuary city policies Tuesday, announcing it would ask a federal court to halt three state laws that prohibit police and businesses from cooperating with federal agents.

Mr. Sessions said California’s laws trample on the federal government’s powers to set national immigration policy.

But beyond the legal questions, the Trump administration says sanctuary laws endanger communities by freeing criminals back onto the streets, putting both immigration officers and others at risk.
