A federal appeals court has made a ruling regarding construction at the White House. The court found that President Donald Trump is unlawfully building a new ballroom. This decision may lead to further action, potentially involving the Supreme Court.

The ruling was made by the DC Circuit Court of Appeals, with a 2-1 decision. The court sided with a historic preservation group that sued over the project. The group had argued that Congress, not the Executive Branch, should decide on such changes to the White House.

Further details on this ruling are available from the source, including the full opinion from the court.
