President Trump’s administration asked the Supreme Court to let it deploy federally controlled National Guard troops in Illinois, seeking to freeze lower-court rulings that blocked their deployment while allowing federalization to continue. In an emergency filing, Solicitor General D. John Sauer said the orders undermine the president’s Commander-in-Chief authority and endanger federal officers amid protests over immigration policy. Illinois and Chicago sued, and a district judge deemed DHS’s assessment unreliable. A unanimous Seventh Circuit panel kept deployment on hold, finding the facts don’t justify Title 10 use. Gov. J.B. Pritzker denounced the move and vowed to defend state sovereignty.
