Trump's executive order threatens federal funding cuts or legal action for cities or states that continue to maintain their sanctuary status.

The Trump administration escalated its showdown with Democratic-led states and cities over immigration enforcement on Monday, announcing that the president will sign executive orders that will “unleash America’s law enforcement to pursue criminals” and direct federal agencies to publish a list of “sanctuary cities” that do not cooperate with immigration agents.

The signings fell on the eve of his first 100 days of his second term, during which he has enacted an immigration crackdown.
