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.

A federal judge in Illinois dismissed a Trump administration lawsuit Friday that sought to disrupt limits Chicago imposes on cooperation between federal immigration agents and local police.

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.
