The Supreme Court rejected the Trump administration’s emergency request to immediately deploy federalized National Guard troops to Chicago, temporarily blocking the plan.

The justices upheld a lower court ruling that said the government failed to show legal authority to use the military to enforce laws in Illinois, with three conservative justices dissenting.

The decision marks a rare setback for President Trump, who has largely prevailed in emergency appeals since returning to office.

Illinois officials praised the ruling, while the White House said the administration will continue pursuing its public safety and immigration enforcement agenda, Fox News has reported.

The case is part of a broader legal battle over Trump’s efforts to deploy National Guard troops to Democratic-led cities despite opposition from state and local leaders.
