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 dismissed a Trump administration lawsuit challenging sanctuary policies for immigrants in Illinois and Chicago.
