CHICAGO - Chicago will sue the Trump administration on Monday over threats to withhold public safety grant money from so-called sanctuary cities, escalating a pushback against a federal immigration crackdown, Mayor Rahm Emanuel announced on Sunday.

The federal lawsuit comes less than two weeks after Attorney General Jeff Sessions announced that the US Justice Department would strip cities of certain grant funds unless they agreed to allow immigration authorities access to local jails and to provide 48 hours' notice before releasing anyone wanted for immigration violations.
