WASHINGTON (AP) — A federal appeals court on Friday ordered President Donald Trump’s administration to halt construction of its $400 million ballroom at the White House because the project lacks congressional approval. The divided appeals court panel upheld an April 16 order from Leon for the Trump administration to halt aboveground work on the ballroom. Attorneys for the preservation group countered that the lack of a White House ballroom doesn’t constitute a national security emergency. In response, the appeals court instructed the judge to reconsider the national security implications of stopping construction. The judge stressed that the White House is free to proceed with underground work, including the construction of any bunkers, military installations and medical facilities.
