Mayor Cherelle L. Parker ’s office declined to comment on Trump’s post Thursday. Parker has been largely quiet on the issue of sanctuary cities, even as activists have increasingly called on her to defend the city’s policy, which former Mayor Jim Kenney made a cornerstone of his tenure.

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.

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.
