The Supreme Court has refused to allow the Trump administration to deploy National Guard troops in the Chicago area to support its immigration crackdown

The US Supreme Court has rejected the Trump administration's bid to deploy National Guard troops in the Chicago area, over the objections of local and state officials. In an unsigned order, the top court said the president's ability to federalise the National Guard likely only applies in "exceptional" circumstances.

The justices denied the Justice Department's request ​to lift a judge's order that has blocked the deployment of hundreds of National Guard personnel in a legal challenge brought by Illinois state officials and local leaders.

The Supreme Court has denied President Donald Trump's request to lift a lower court injunction against his deployment of National Guard troops in Chicago and across Illinois to support immigration enforcement operations.

The US Supreme Court refused to let President Donald Trump start deploying National Guard troops in Chicago, dealing a setback to his drive to use the military in liberal cities across the country.

An unsigned 6-3 ruling says the administration failed to show it had legal authority to send troops over the objections of state and local officials.

Trump's federalization of the National Guard has sparked a fierce debate across party lines, as Democrats denounce the push as unlawful and beyond the scope of his authority.

The Supreme Court on Tuesday barred President Donald Trump from deploying the National Guard to Chicago to protect ICE agents, handing the White House a rare loss at the high court as the president has sought to send troops to multiple American cities.
