President Donald Trump drew bipartisan criticism Saturday after posting an AI-generated image on Truth Social that depicted him as a wartime commander and included language suggesting the federal government might use military force in U.S. cities, including Chicago.

The post paired a digitally altered image styled after Robert Duvall’s character in the film "Apocalypse Now" with the line, "I love the smell of deportations in the morning…" and the message, "Chicago about to find out why it’s called the Department of WAR," a reference to an executive order Mr. Trump signed renaming the Department of Defense. The image also displayed the words "Chipocalypse Now." Several Democratic elected officials described the post as an unacceptable threat to American cities and the Constitution.

California Gov. Gavin Newsom said on X that the president was "using our troops like political pawns" and warned Americans not to become "numb" to such actions. Newsom has sparred with the White House previously after National Guard troops and Marines were deployed to Los Angeles over the summer to support federal immigration enforcement and respond to demonstrations.

Illinois Gov. J.B. Pritzker wrote on X that "the President of the United States is threatening to go to war with an American city" and called the behavior "not normal." Chicago Mayor Brandon Johnson characterized the post as an attempt to "occupy our city and break our Constitution," calling the threats "beneath the honor of our nation." Johnson has repeatedly said he would resist federal intervention and cited city data showing declines in violent crime, including homicides and robberies down more than 30% and shootings dropping by nearly 40% from the previous year.

Illinois Sens. Tammy Duckworth and Dick Durbin also criticized the post. Duckworth, a combat veteran and retired Army National Guard lieutenant colonel, wrote on X, "No Donald, Chicago is not your war zone." Durbin said the president should focus on domestic issues such as weak jobs reports, a rise in measles cases, tariffs affecting farmers and businesses, and unresolved matters related to Jeffrey Epstein rather than "asking ChatGPT to make him memes and threatening to turn our brave armed forces against American cities."

The post came as federal officials have discussed the possibility of deploying the National Guard to Chicago to address crime, a step Illinois leaders have opposed. The Biden administration’s predecessors and Mr. Trump’s own administration have at times used federal forces and National Guard units in responses to civil unrest and enforcement actions, drawing debate over the proper role of the military in domestic law enforcement.

White House officials did not immediately respond to requests for comment on the post Saturday. The exchange adds to a widening public dispute between the White House and Illinois officials who have resisted federalization of law enforcement in the city. Mr. Trump and Illinois leaders have traded public barbs in recent weeks over crime, federal assistance and political authority.

Legal scholars and constitutional experts have long warned that using federal troops for domestic policing raises complex legal and civil liberties questions, particularly when governors and local officials object. The Posse Comitatus Act limits the military's role in civilian law enforcement, though exceptions exist for the National Guard when activated by state governors and for other federal deployments under certain circumstances.

Mr. Trump's use of social media to promote provocative imagery and messaging has been a persistent feature of his political communication. The latest post, which used artificial intelligence to create a cinematic likeness, underscores ongoing debates about the use of AI in political messaging and the potential for such content to inflame tensions.

Democratic officials said the post crossed a line by evoking military force against American communities. Republican reactions were more mixed, with some allies defending the president's tough-on-crime rhetoric and others expressing concern about the implications of federal troops on U.S. streets. The incident is likely to intensify scrutiny of any federal moves regarding Chicago and could sharpen rhetorical and legal confrontations between the Trump administration and state and local leaders as the debate continues.
