The U.S. Supreme Court ruled Tuesday that President Donald Trump has not shown sufficient legal authority to federalize National Guard troops in Chicago, temporarily blocking their use to assist federal immigration enforcement while the case moves forward.
In a 6–3 decision from the court’s emergency docket, the majority said federal law generally limits the military’s role in civilian law enforcement, and that the administration failed to justify an exception.
Justice Brett Kavanaugh agreed with denying the request, but warned the ruling could limit a president’s ability to protect federal personnel and property; while three conservative justices dissented. The White House said the decision would not change Trump’s immigration agenda. The ruling applies only during the ongoing legal challenge, but marks the court’s first direct response to Trump’s National Guard deployments in multiple cities.
