President Donald Trump escalated his confrontation with Chicago on Saturday, threatening the city with action from his newly rebranded “Department of War” in a post that sparked outrage from Illinois leaders.
“I love the smell of deportations in the morning… Chicago is about to find out why it’s called the Department of War,” Trump wrote on Truth Social, alongside an edited image depicting himself as a character from the Vietnam War film Apocalypse Now. The image bore the slogan “Chipocalypse Now” over a burning city skyline.
Illinois Governor J.B. Pritzker condemned the post as a dangerous provocation. “The President of the United States is threatening to go to war with an American city,” Pritzker wrote on X. “This is not a joke. This is not normal. Donald Trump isn’t a strongman, he’s a scared man. Illinois won’t be intimidated by a wannabe dictator.”
Chicago Mayor Brandon Johnson accused the president of authoritarianism. “The President’s threats are beneath the honor of our nation, but the reality is that he wants to occupy our city and break our Constitution,” Johnson said in a statement.
The remarks came a day after Trump issued an executive order renaming the Department of Defense as the Department of War. At a press conference on Friday, Secretary of War Pete Hegseth said the name change signaled a new posture. “We’re going to go on offense, not just on defense. Maximum lethality, not tepid legality. Violent effect, not politically correct,” Hegseth declared.
Trump has repeatedly singled out Chicago in recent weeks, citing crime and immigration as justification for potential federal intervention. His threats follow the deployment of National Guard troops to Washington, D.C., on August 11, when he also moved to federalize the city’s police force. Despite Trump’s claims of surging violence, official data showed crime rates in the capital were already falling.
Chicago officials have braced for a similar move. Last weekend, Mayor Johnson signed an executive order directing the city’s police not to cooperate with federal agents in the event of a federal crackdown. “We will protect our Constitution. We will protect our city. And we will protect our people. We do not want to see tanks in our streets. We do not want to see families ripped apart,” Johnson said.
Governor Pritzker has pledged to challenge any deployment in court, adding to several lawsuits already filed by Chicago against Trump’s administration since his return to office in January. “If the president sends troops into Illinois, we will absolutely sue,” Pritzker said.
The escalating dispute underscores the widening gulf between Trump’s hardline security agenda and city and state leaders who accuse him of undermining constitutional norms.
