Appeals court rules Trump's White House ballroom construction is unlawful and potentially illegal

A divided federal appeals court ruled Friday that President Donald Trump is unlawfully constructing a massive new ballroom at the White House, possibly teeing up a high-stakes showdown over the issue. The construction of the $35 million project has been criticized by preservationists and lawmakers who argue it violates historic preservation laws. A potential appeal to the Supreme Court could be on the horizon if Trump decides to pursue the matter further.
