Donald Trump is turning up the pressure once again: this time threatening to use the Insurrection Act to send U.S. troops into Chicago. The statement comes as tensions rise between Trump and Democratic city leaders, including Illinois Governor JB Pritzker and Chicago Mayor Brandon Johnson, who have pushed back against his immigration and public safety policies.
Trump suggested that if city and state officials can’t “get control” of violent crime or cooperate with federal enforcement, he may consider invoking the Insurrection Act: a rarely used federal law that allows the President to deploy the military on U.S. soil.
Legal experts warn that actually invoking the act would mark one of the most dramatic uses of executive power in modern U.S. history.
What Is the Insurrection Act?
The Insurrection Act is a centuries-old law that gives the President authority to use the military to restore order during serious unrest or rebellion. It’s one of the only legal ways for a president to send troops into American cities without a governor’s permission.
The law dates back to 1807 and has been used only a handful of times—mostly during major crises. President Eisenhower and Kennedy used it to enforce school desegregation in the 1950s and 1960s, and George H.W. Bush invoked it in 1992 during the Los Angeles riots after the Rodney King verdict.
Normally, U.S. troops can’t act as police inside the country because of a separate law called the Posse Comitatus Act, which prevents the military from handling civilian law enforcement. The Insurrection Act is the one big exception to that rule.
If Trump were to use it, he could send active-duty soldiers or federalized National Guard troops into Chicago to enforce laws, control protests, or assist police—all without needing the governor’s approval.
Trump’s comments are part of a growing standoff between his administration and several Democratic-led cities.
Alongside his recent calls for the arrest of Pritzker and Johnson, this new threat adds another layer of political tension as the federal government navigates shutdowns, immigration disputes, and street protests.
If Trump were to follow through, it would be one of the most corrupt use of military power against American citizens in decades.
For now, Chicago officials say they’re focused on community-based safety solutions; not troops in the streets.
