The man that President-elect Donald Trump has tapped to be his border czar, Tom Homan, has made a bombshell promise in a massive blue city.

He was on hand in Chicago, a city whose mayor has vowed to fight the Trump administration on its deportation plans, where he said he would start on “day one.”

He gave the comments on Monday at a Christmas party hosted by the Northwest Side GOP, WFLD-TV reported

“January 21st, you’re going to look for a lot of ICE agents in your city, looking for criminals and gang members,” he said, indicating that the deportations would start the day after the inauguration of the president-elect.

The governor’s office responded to the comments with blistering words.

“It’s no secret that Illinois will face countless, baseless attacks over the next four years from the Trump Administration. Rather than responding to every ridiculous boast from Trump lackeys, Governor Pritzker is focused on what he was focused on during the first Trump term: leading our state with competence instead of chaos,” it said.
