The Trump administration has filed a lawsuit against Illinois, the City of Chicago and Cook County over its sanctuary status. The complaint was filed in federal court in Chicago. It names the state, Chicago and Cook County as defendants.

The federal lawsuit is the first by Trump's Justice Department against states or municipalities that have sanctuary city policies.

Federal officials are asking a judge to bar the Illinois, Chicago, Cook County and the Cook County Sheriff from using local laws that protect migrants to hamper law enforcement.
