Ukraine–Russia War

In a 6–3 emergency ruling the Supreme Court blocked the Trump administration’s plan to deploy the Illinois National Guard to Chicago, finding the president had not shown why the city’s circumstances justified an exception to the Posse Comitatus Act and interpreting the statute’s reference to “regular forces” as meaning the U.S. military rather than civilian law‑enforcement agencies. Justice Samuel Alito, joined by Clarence Thomas, sharply dissented — calling the majority’s decision “unwise” and faulting the Court for failing to defer to the president and adopting an “eleventh‑hour” statutory argument — while Justice Neil Gorsuch filed a separate dissent; the administration had contended ICE officers were being obstructed and threatened and local authorities were not adequately responding, and the emergency order formally applies only to the Illinois case though it may influence other deployment disputes.
