Overview

• Mayor Brandon Johnson signed an executive order prohibiting Chicago police from assisting civil immigration enforcement, joint patrols, traffic stops or checkpoints, and barred officers from masking their identities.
• Homeland Security Secretary Kristi Noem confirmed the administration will add resources to ICE operations in Chicago, offering no agent counts or timelines after a logistical request tied to Naval Station Great Lakes surfaced.
• Illinois Governor J.B. Pritzker and Johnson said they were not consulted, denounced a potential deployment as unconstitutional overreach, and warned they will sue if federal forces are sent.
• A federal judge, Charles R. Breyer, ruled the earlier Los Angeles troop deployment illegal under the Posse Comitatus Act, allowing only building protection if any personnel remain and setting a constraint that could weigh on plans for Chicago.
• President Donald Trump called Chicago the most dangerous city in the world and threatened to send troops after a weekend with at least seven dead and 47 wounded in shootings, as some reports cite unnamed officials indicating a possible short-term surge beginning around September 5 that has not been confirmed.
