Trump Says Chicago ‘Will Find Out Why It’s Called the Department of WAR’
Introduction
President Donald Trump has once again sparked controversy, this time targeting Chicago, one of the nation’s largest cities, with bold threats ahead of a planned immigration crackdown. On Saturday, Trump shared a meme declaring that Chicago “will find out why it’s called the Department of WAR,” following his executive order to rebrand the Pentagon as the “Department of War.”
The post has ignited fierce backlash from Illinois officials, Chicago’s mayor, and Democratic leaders nationwide. As federal personnel deploy to Chicago and National Guard intervention remains on the table, the move raises serious legal, political, and constitutional concerns.
Trump’s Explosive Meme and the Pentagon Rebrand

On Saturday, Trump posted a meme featuring an AI-generated image of himself wearing sunglasses and a cavalry hat, standing against the Chicago skyline. The text read:
“I love the smell of deportations in the morning … Chicago about to find out why it’s called the Department of WAR.”
This comes just a day after Trump signed an executive order officially rebranding the Pentagon from the “Department of Defense” to the “Department of War” — a symbolic but politically charged move that signals an aggressive stance on both immigration and national security.
The meme quickly went viral, drawing widespread criticism from political leaders who accused the president of threatening violence against an American city.
Planned Immigration Crackdown in Chicago
Behind the heated rhetoric lies a significant policy shift. According to CNN, the Trump administration is preparing to conduct a large-scale immigration enforcement operation in Chicago, potentially starting as early as Friday.
Key Details of the Planned Operation:
- Personnel from Immigration and Border Protection and Customs and Border Protection have already started arriving in Chicago.
- Federal officials have confirmed that the National Guard could be deployed if the situation escalates.
- The crackdown is modeled after a June 2025 Los Angeles operation, which was later ruled illegal by a federal judge.
Despite the court ruling, the Trump administration has appealed the decision, maintaining that Chicago’s situation “warrants immediate and decisive action.”
Backlash From Illinois Leaders
Illinois leaders, including Governor JB Pritzker and Chicago Mayor Brandon Johnson, have condemned Trump’s statements and plans, calling them a direct threat to democracy.
Governor Pritzker’s Response:
“The President of the United States is threatening to go to war with an American city. This is not a joke. This is not normal. Illinois won’t be intimidated by a wannabe dictator.”
Mayor Brandon Johnson’s Statement:
“The President’s threats are beneath the honor of our nation. He wants to occupy our city and break our Constitution. We must defend Chicago and our democracy.”
National Guard Deployment: A Legal Gray Area

The Trump administration has left the door open to deploying National Guard troops in Chicago, a move fraught with legal and constitutional challenges.
Under the Posse Comitatus Act, the U.S. military is largely prohibited from engaging in domestic law enforcement. The June Los Angeles operation violated this federal law, but Trump’s administration is pushing boundaries again.
If Trump moves forward, expect federal lawsuits and potential battles in the Supreme Court over executive authority.
Reactions From Congress and National Leaders
Lawmakers across the country are expressing alarm over Trump’s escalating rhetoric:
- Senator Tammy Duckworth (D-IL) accused Trump of “stolen valor,” referencing his meme photo: “Take off that cavalry hat, you draft dodger. You didn’t earn the right to wear it.”
- Rep. Mike Quigley (D-IL) warned that Trump’s actions are “edging more and more toward authoritarianism”: “This is a scary time. For those who haven’t paid attention, it’s time to start watching what this president is doing.”
Chicago’s History With Federal Crackdowns

This isn’t the first time Trump has clashed with Chicago leadership. In the past, he has threatened to “send in the feds” to address crime and immigration in the city. However, this time is different due to:
- The Pentagon’s rebranding to the “Department of War.”
- The scale of the planned immigration operation.
- The possibility of National Guard involvement.
These escalations suggest a broader political strategy aimed at portraying Chicago as a symbol of federal toughness on immigration.
Impact on Immigrant Communities
For Chicago’s large immigrant population, the looming crackdown has already created an atmosphere of fear. Community advocacy groups are reporting:
- Increased calls to legal aid hotlines.
- Rising concerns over family separations.
- Heightened tensions between residents and federal agents.
The American Civil Liberties Union (ACLU) has promised to challenge any unconstitutional deportation efforts.
Political Stakes for Trump
Trump’s Chicago strategy may be tied to election-year politics. By taking an aggressive stance, he appeals to his base on:
- Border security
- Law-and-order messaging
- Challenging liberal cities
However, the move risks alienating moderate voters and could fuel further polarization nationwide.
What Happens Next?
The coming days are critical. Here’s what to watch:
- Whether National Guard troops are officially deployed.
- Federal court challenges over the legality of the crackdown.
- Rising political clashes between the Trump administration and Illinois officials.
- The response from immigrant-rights organizations.
If tensions continue to escalate, Chicago could become ground zero for a broader national battle over immigration, executive power, and civil rights.
