A federal appeals court ruled Friday that President Donald Trump lacks the authority to build a $400 million ballroom at the White House without congressional approval. In response to the ruling, President Trump wrote in a Truth Social post that he “will be immediately appealing to the United States Supreme Court” and described the decision as “horrendous, politically motivated, and unlawful.” In a 2-1 decision, the appeals court affirmed a lower court’s finding that the White House “very likely” lacked the authority to proceed with the ballroom project. The appeals court’s ruling explicitly leaves in place a lower court decision allowing construction of the presidential bunker to continue. “The White House, a global landmark that symbolizes American identity and the ideals of democracy, belongs to the American people.”
