–CHICAGO (AP) — The U.S. Justice Department contends the city of Chicago and Cook County violated federal immigration laws when they were awarded public safety grants last year. The assertion was made in letters to Chicago police Superintendent Eddie Johnson and Cook County Board President Toni Preckwinkle. The Justice Department gives them until Oct. 27 to prove otherwise. Emanuel says he rejects the administration’s stance. A Preckwinkle spokesman says the county is in compliance with applicable federal laws.
