The president moved this week to counter legal defeats on ending birthright citizenship and firing a Fed governor, while seeking the justices' help with his ballroom.
An appeals court ruled earlier Friday that construction must stop until Congress authorizes the project. The ballroom is among the president's top priorities for this term.
A federal appeals court panel backed a lower court's ruling, and made it likely that the Supreme Court will decide the case. But the decision does not mean construction will halt immediately.
