Faced with a threat of stepped-up enforcement in New York by Donald Trump’s new border czar, top New York court officials are laying down the law and saying they will continue to shut their doors to federal immigration authorities looking to round up undocumented immigrants as they seek to launch mass deportation proceedings in the Empire State.

Mayor Eric Adams said Tuesday he opposed mass deportation plans by President-elect Donald Trump, but he is willing to work with his incoming administration on immigration. The comments came during a contentious news conference held as Trump has already named officials pledging to conduct immigration raids in New York and beyond.

President-elect Donald Trump’s immigration promises mirror those of his first term, including the mass deportations of millions of undocumented immigrants and tightening the border.
