A federal judge threw out the Trump administration's lawsuit against Illinois, Cook County and Chicago sanctuary policies that ban assisting in immigration-related matters.

The Justice Department had sued the leaders of Illinois, Chicago and Cook County over policies that limit cooperation with federal immigration officials.

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.
