Trump Signals He Could Invoke Insurrection Act if Courts Block National Guard Deployments

President Donald Trump said he would consider invoking the Insurrection Act to deploy active-duty military forces domestically if federal courts continue to thwart his attempts to send National Guard units to Democrat-run cities, intensifying a legal and political standoff between the White House and several states.

The comments came amid fast-moving litigation over the administration’s efforts to federalize Guard troops for missions in Portland and Chicago. In Oregon, a federal judge twice issued temporary orders halting Guard deployments while state lawsuits proceed. In Illinois, however, a different federal judge declined to immediately block the administration, allowing preparations for a Chicago-area deployment to continue for now.

Pressed on next steps if judges prevent Guard deployments, Trump said the Insurrection Act remains on the table, arguing it exists for precisely such circumstances. He suggested he could use it if people were being killed and courts or local officials were “holding us up.” (He has previously floated the option in public remarks.)

The Insurrection Act of 1807 is a narrow exception to the Posse Comitatus Act’s ban on using the military for domestic law enforcement. It has been invoked rarely in modern times and not without state consent for over half a century, according to legal analysts. If used, it would permit active-duty troops—or federalized Guard—to perform policing functions typically reserved for local authorities.

Illinois and Chicago on Monday sued to block Trump’s move to federalize the state’s Guard and to prevent troops from other states being sent to Illinois, describing the deployments as unconstitutional and harmful. A similar challenge from Oregon led to a temporary restraining order over the weekend, after the administration tried successive workarounds by sourcing Guard units from neighboring states.

The court clashes highlight a broader pattern in which even some judges appointed by Trump have ruled against high-profile administration initiatives, drawing public ire from the president. The White House, for its part, argues lower courts are obstructing needed public-safety measures and says it expects relief on appeal.

What happens next will turn on parallel tracks: expedited appeals over Guard deployments in Oregon and Illinois, and the White House’s decision on whether to trigger the Insurrection Act—an extraordinary step that would test long-standing limits on federal power in domestic law enforcement.
