The judge determined the state's policies are protected by the 10th Amendment, a blow to Trump's efforts to crack down on sanctuary jurisdictions.

The ruling is a setback for Trump, the first defeat in a series of similar lawsuits the Justice Department filed against states and cities that have adopted sanctuary policies that limit their employees’ cooperation with federal immigration enforcement. Other suits have been filed against cities in California, New Jersey and New York.

U.S. District Court Judge Lindsay C. Jenkins for the Northern District of Illinois Eastern Division said the Trump administration “lacks standing” to invalidate the state, city and county laws that limit cooperation with federal immigration enforcement.
