Overview

• U.S. District Judge April Perry issued a temporary order blocking the deployment in Illinois until Oct. 23, saying sending troops would “add fuel to the fire.”
• Roughly 500 Guard members were mobilized for the Chicago area — about 300 from Illinois and 200 from Texas — with some Texas troops already working near Chicago after staging at an Army Reserve center in Elwood.
• Chicago and Illinois sued to stop the operation, arguing protests at the Broadview ICE facility never impeded enforcement; Perry cited a separate ruling that curtailed federal agents’ use of force at the site.
• The White House said it will appeal, and President Trump has floated invoking the Insurrection Act; he also publicly called for jailing Mayor Brandon Johnson and Gov. J.B. Pritzker.
• Parallel litigation continues over Portland, where a prior order blocking a Guard deployment is before a 9th Circuit panel, positioning the courts to set key limits on domestic troop use.
