President Donald Trump’s Truth Social post saying Chicago was about to find out “why it’s called the Department of War” drew swift rebuke from Illinois leaders Saturday morning.

“‘I love the smell of deportations in the morning,’” he posted on Truth Social, a reference to the 1979 war movie “Apocalypse Now.” “Chicago about to find out why it’s called the Department of War,” the post continued, including an image of him dressed in an Army uniform and helicopters flying in the background with the words “Chipocalypse Now,” a reference to the 1979 war film.

Trump signed an executive order Friday authorizing the Department of War as a secondary title for the Department in a move that he said sends “a message of strength.”

Gov. JB Pritzker responded to Trump’s deportations post Saturday on X, saying it “is not normal.”

“The President of the United States is threatening to go to war with an American city,” Pritzker said in the post.

“This is not a joke. This is not normal.”

Speaking from the 24th annual Mexican Independence Day Parade in Pilsen Saturday, Sen. Dick Durbin called the post “disgusting.” “To suggest that the troops are coming into Chicago is an embarrassment,” he said.

The post comes as Trump ramps up federal enforcement in Chicago and the city is bracing for preparing for anticipated increased operations by ICE. On Wednesday, Pritzker said he expects ICE agents to “begin actions on Saturday or over the weekend.”
