Overview

• U.S. Northern Command says about 500 National Guard members — roughly 200 from Texas and 300 from Illinois — are mobilized for at least 60 days and based at the Elwood Army Reserve Center, where new fencing, privacy screens and temporary housing have been set up.
• The mission focuses on protecting ICE personnel and facilities with security perimeters, crowd-control and de-escalation, and troops may temporarily detain to prevent interference but are not authorized to make arrests.
• An element of the Texas contingent began protecting federal property in the Chicago area on Wednesday, according to an official who spoke to the Associated Press, as protests continued in the city and at the Broadview ICE site.
• Illinois and Chicago are asking a federal judge to halt the deployment at a hearing Thursday, while a separate 9th Circuit panel weighs a Portland case after a trial judge blocked deployments there and another court found a Los Angeles use violated the Posse Comitatus Act.
• President Trump urged the jailing of Mayor Brandon Johnson and Governor JB Pritzker over their resistance, Homeland Security Secretary Kristi Noem backed prosecution of officials she says endanger federal officers, and the White House has floated possible Insurrection Act invocation as a Reuters/Ipsos poll found most Americans oppose such deployments without an external threat.
