President Donald Trump’s travel ban executive order suffered another legal blow Monday as a second federal appeals court weighed in against the legality of the directive.

A three-judge 9th Circuit panel unanimously turned down a Trump administration request to lift an injunction blocking key parts of Trump’s revised order from taking effect.

Trump “exceeded the scope of the authority delegated to him by Congress” to oversee immigration, the court ruled. “Immigration, even for the President, is not a one-person show,” the three judges wrote in a joint opinion.

Last month, another federal appeals court—the 4th Circuit—also rebuffed Trump’s effort to move forward with the directive, which he contends is an anti-terrorism measure.

The Supreme Court is already considering the Justice Department’s requests to consider the issue and allow Trump’s order to take effect in the meantime.
