(Reuters) -A U.S. federal judge on Friday blocked Donald Trump's administration from withholding federal funding from more than 30 so-called sanctuary jurisdictions including Los Angeles, Baltimore, Boston and Chicago that have declined to cooperate with the Republican president's hardline immigration crackdown.

A judge has ruled the Trump administration cannot deny funding to Boston, Chicago, Denver, Los Angeles and 30 other cities and counties because of policies that limit cooperation with federal immigration efforts.
