Supreme Court Blocks Trump’s Emergency National Guard Deployment to Chicago
Updated (2 articles)
Supreme Court Issues Brief Order Denying Emergency Request The high court issued an unsigned, brief order on Dec. 23, 2025, rejecting the Trump administration’s emergency petition to lift U.S. District Judge April Perry’s block on deploying the Illinois National Guard to Chicago [1][2]. The order does not address the substantive legal questions and leaves the lower‑court injunction in place. It represents a rare emergency‑docket denial for the White House’s immigration‑enforcement strategy.
Three Conservative Justices Register Dissent Justices Samuel Alito, Clarence Thomas and Neil Gorsuch filed dissenting statements, signaling continued disagreement over the president’s authority to federalize the Guard for civilian immigration duties [1][2]. Their dissent underscores a split within the Court on the scope of executive power in domestic deployments. The dissent did not alter the outcome but highlighted ideological divisions.
Lower Court Block and State Officials Respond Judge April Perry’s earlier injunction barred the Guard’s activation, a decision the Supreme Court left untouched [1][2]. Illinois Governor JB Pritzker praised the ruling as a victory for state sovereignty and warned that Trump lacked authority to deploy militia in Illinois [1]. Attorney General Kwame Raoul echoed the sentiment, noting that the circumstances required for militia activation do not exist in the state [2].
White House Maintains Immigration Enforcement Agenda White House spokesperson affirmed that the administration will continue to enforce immigration laws and protect federal personnel, despite the setback [1][2]. The statement reiterated that the Guard was intended to shield ICE agents and federal buildings from potential damage. Officials indicated that other enforcement tools remain available to pursue the president’s agenda.
Court Narrows Definition of “Regular Forces” The unsigned order clarified that “regular forces” likely refers only to the standing military, not civilian federal agents, thereby limiting presidential deployment powers [2]. Justice Brett Kavanaugh warned the interpretation could affect future crises involving federal facilities. Analysts noted the Insurrection Act remains a politically fraught, albeit possible, alternative for federal troop deployment [2].
