President Donald Trump on Saturday posted what appears to be an artificial intelligence-generated image of himself in front of the Chicago skyline, complete with helicopters, flames and the phrase “Chipocalypse Now.”

The president’s post appears to threaten Chicago with troops and deportations, prompting a backlash from Democratic leaders in Illinois.

“Love the smell of deportations in the morning?” Chicago about to find out why it’s called the WAR Department,” reads the president’s post on Truth Social, appearing to reference the 1979 film “Apocalypse Now,” which depicts the U.S. War in Vietnam.

The post also appeared to reference an executive order Trump signed Friday renaming the Department of Defense the War Department and the Secretary of Defense the Secretary of War.

Illinois Democratic Gov. J.B. Pritzker on Saturday called Trump’s post “abnormal.”

“The President of the United States is threatening to declare war on an American city. This is not a joke. “This is not normal,” Pritzker wrote in X. “Donald Trump is not a dictator, he’s a scared man. Illinois will not be intimidated by a would-be dictator.” Illinois officials have warned that President Trump could soon order troops, Immigration and Customs Enforcement agents, and other federal law enforcement officers to Chicago to carry out his policies of carrying out mass deportations and fighting crime, as he previously ordered in Washington, D.C. But White House officials have made clear that the immigration crackdown in Chicago is distinct from the president’s decision to use federal law enforcement and National Guard troops to wage a crime crackdown in the city. Asked by a reporter Tuesday about sending National Guard troops to the city, Trump replied, “We’re coming.” and added: “I didn’t say when. We’re going in.”

Other Democratic officials representing Chicago and Illinois also condemned Trump’s post Saturday.

“The President’s threats belittle the honor of our nation, but the reality is he wants to occupy our city and break our Constitution,” Chicago Mayor Brandon Johnson wrote on social media. “We must defend our democracy from this authoritarianism by protecting each other and by protecting Chicago from Donald Trump.”

Senator Dick Durbin, Democrat of Illinois, spoke to reporters during Mexican Independence Day celebrations in Chicago, calling Trump’s post “disgusting.”

“His tweet this morning was disgusting. To insinuate that troops are going to come into Chicago or that the War Department is going to intervene is disgraceful,” said Senator Durbin.

In recent weeks, Trump has threatened to deploy National Guard troops and federal law enforcement officers to several U.S. cities led by Democratic mayors, including Baltimore and New Orleans.

For the most part, the Democratic mayors have opposed Trump’s plans and responded by questioning why their cities are plagued by crime, pointing to declining crime rates.
