A federal appeals court has made a ruling regarding a construction project at the White House. The project in question is a $400 million ballroom. According to the court, the administration must stop construction because Congress has not approved the project.

The court's decision stated that the president does not have the authority to unilaterally build the ballroom. The administration plans to appeal the decision to the US Supreme Court. Further details about the ruling and the project are available from the source, including the president's response to the decision.
