US mayors decry Trump sanctuary city threat

Democratic US mayors said on Friday their cities would welcome illegal immigrants, dismissing President Donald Trump's threats to transport people detained at the border to "sanctuary cities" as illustrating the White House's callous approach to the issue. Trump confirmed on Twitter that he wanted to transport people detained in his immigration crackdown at the US-Mexico border to sanctuary cities, an informal designation for localities that refrain from assisting federal immigration authorities in detaining people living in the country illegally.
