National Guard & Federal Authority

The Supreme Court denied the Trump administration’s emergency request to federalize and deploy National Guard troops to the Chicago area, leaving Judge April Perry’s injunction in place and issuing an unsigned 6–3 order saying, at this preliminary stage, the government had not shown a legal basis under the Posse Comitatus framework to use the military to execute domestic law. Justices Alito, Gorsuch and Thomas dissented (with Kavanaugh filing a separate concurrence), the court accepted the lower courts’ fact‑finding, a Texas contingent was sent home, and reactions split between Illinois Gov. J.B. Pritzker, who hailed the ruling, and the White House, which said it did not undermine the administration’s immigration and public‑order agenda.
