CHICAGO — Illinois Gov. JB Pritzker said he’s open to working with President-elect Donald Trump’s new border czar — but said he was skeptical the incoming official had the “authority” to do everything he said.

“Being a border czar is not an official position in the government, and it will be up to the President of the United States and up to the leaders of the Customs and Border Patrol to make decisions about how we’ll manage the border,” Pritzker said.

Trump’s incoming border czar, Tom Homan, visited Chicago on Monday and said both Pritzker and Chicago Mayor Brandon Johnson “suck” for their comments about not working with federal agents on deportations. Illinois is a sanctuary state and Chicago is a sanctuary city, meaning there are laws and ordinances that prevent local law enforcement from working with ICE.

Homan spoke at a Chicago GOP gathering and said the city would be ground zero for “the biggest deportation operation this country has ever seen.”

Pritzker dismissed Homan’s comments as political rhetoric but said he should be “serving Democrats and Republicans. If you take a position in the executive branch, you serve all of the people of the United States.”

Pritzker said he agrees that “violent criminals who are undocumented and convicted of violent crime should be deported.” Asked if that meant he would work with federal agents to allow deportation of convicted violent criminals, Pritzker said, ‘Yes. Sure, just as I do every day with federal and state law enforcement on other matters.”

Trump has also promised to bring in National Guard units to help in the new administration’s deportation efforts. Pritzker said he would reject any attempt to use the Illinois National Guard to assist ICE, and he would reject Guard units from other states coming to Illinois.

“I do not believe that we should be pitting one state’s National Guard against another state,” said Pritziker. “I think that’s un-American.”
