At the same time, the Trump administration has directed immigration officers to pause arrests at farms, restaurants and hotels, after Trump expressed alarm about the impact aggressive enforcement is having on those industries, according to a U.S. official familiar with the matter who spoke only on condition of anonymity.

Chicago is among the cities listed in President Trump's new call for what he's calling the "single largest mass deportation program in history." In a social media post on Sunday, Mr. Trump ordered ICE to expand efforts in cities he called "the core of the Democratic power center.

He wrote Sunday on Truth Social that he instructed his entire administration "to put every resource possible behind this effort."
