The US Court of Appeals for the DC Circuit, which had allowed construction to continue while it considered the case, agreed with a lower court that such a massive White House overhaul required the explicit consent of Congress. It stayed its own decision for two weeks to give Trump time to ask the Supreme Court to intervene. Trump, who has repeatedly complained that the White House lacks sufficient space for grand galas such as state dinners, unilaterally ordered construction of the massive ballroom. While the White House initially cited a US$200-million price tag for the project, it quickly doubled the estimate to US$400 million. Several of the projects have similarly faced legal challenges, but the ballroom project would be the first to reach the Supreme Court.
