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.

On Feb. 5, the U.S. Department of Justice filed a relatively terse 23-page complaint accusing the combined governments and officials of violating the supremacy clause of the U.S. Constitution. The lawsuit alleged the "so-called" sanctuary policies at issue provide non-citizens "safe havens from federal law enforcement detection."

A federal judge in Chicago on Friday blocked the Trump administration’s challenge to policies in the state of Illinois, the city of Chicago and Cook County that limit the powers of state and local police in assisting federal law enforcement on immigration-related matters.
