Illinois Gov. JB Pritzker called out Donald Trump for planning what he described “an invasion with U.S. troops” in Chicago, while laying out what he believes are the president’s true motivations for targeting the Windy City.

In an interview with CBS’s “Face the Nation” broadcast on Sunday, Pritzker warned the state would respond if Trump goes ahead with his Chicago crime crackdown, which could reportedly happen as soon as this week.

“We hope that they don’t send any troops along with ICE, and if they do, they’ll be in court pretty quickly, because that is illegal,” he said.

Officials told The Washington Post last month that the administration has long been mulling a “military intervention” in Chicago as well as an expanded action by Immigration and Customs Enforcement to identify undocumented migrants in the city.

Trump has repeatedly described crime in Chicago as “TOTALLY OUT OF CONTROL” and, over the weekend, called Pritzker “weak and pathetic,” warning that “he better straighten [crime] out, FAST, or we’re coming!”
