A federal appeals court has made a ruling regarding a construction project at the White House. The Trump administration had planned to build a large ballroom, but the court has ordered construction to be halted. The project in question is a 90,000-square-foot ballroom with a price tag of $400 million.

The court's decision is based on the determination that President Donald Trump does not have the authority to proceed with the project without approval from Congress. Further details about the ruling and the project are available from the source.
