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

The lawsuit asks the court to immediately end a number of laws and ordinances it says thwart federal immigration authorities.

The lawsuit argues the U.S. Constitution’s Supremacy “prohibits Illinois, Chicago, Cook County, and their officials from obstructing the Federal Government’s ability to enforce laws that Congress has enacted or to take actions entrusted to it by the Constitution.”
