President Donald Trump promised to halt federal funding to cities with "sanctuary" policies, including New York City, as part of his crackdown on illegal immigration.

President Donald Trump said that he plans to withhold all federal funding to sanctuary cities, a move that would pressure finances from New York to San Francisco.

Sanctuary cities and states have begun responding to President Donald Trump's threat of revoking their federal funding if they maintain their policies. Officials in California and New York told Newsweek that they will continue to protect immigrants in their communities but also made it clear they will not hinder the federal government's enforcement operations.
