The suit asserts that sanctuary laws in Chicago, Cook County and Illinois have obstructed federal efforts to enforce immigration policy.

SPRINGFIELD – Illinois participated in one court battle with the Trump administration Thursday when a federal judge temporarily blocked enforcement of an executive order that sought to end “birthright citizenship” under the U.S. Constitution.

President Donald Trump promised to make immigration enforcement a top priority for his new administration, and in his first few weeks in office, ICE officials have conducted multiple raids around the country, along with opening up Guantanamo Bay as a detention center to hold up to 30,000 people being deported.
