A federal appeals court appeared skeptical on Monday of lawyers challenging President Donald Trump‘s use of the Alien Enemies Act, as his reliance on the 18th-century law appears increasingly poised to reach the Supreme Court.

During a hearing in a New Orleans courtroom, the judges appeared more skeptical of attorneys from the American Civil Liberties Union who questioned the lawfulness of Trump invoking the Alien Enemies Act. The panel hearing arguments Monday included Judges Leslie Southwick, an appointee of former President George W. Bush; Andrew Oldham, a Trump appointee; and Irma Ramirez, an appointee of former President Joe Biden.
