Overview

• Mayor Brandon Johnson signed the order Saturday, directing that Chicago police will not collaborate with National Guard troops or federal agents on patrols, arrests or civil immigration enforcement.
• The directive requires police to wear full uniforms, display identification, follow body‑camera procedures and avoid masks so they are clearly distinguishable from federal personnel.
• Johnson said the city is prepared to sue to block any unauthorized deployment, and Gov. J.B. Pritzker warned such action would be unconstitutional without state request.
• The White House dismissed the order as a publicity stunt, while reporting notes presidential authority to deploy troops is constrained by law even as agencies like ICE face fewer limits.
• Politico reported a DHS memo seeking to use Naval Station Great Lakes for immigration operations near Chicago, and Johnson said he expects an influx of federal agents as early as Friday.
