Trump asks US Supreme Court to allow construction of White House ballroom

Trump administration has asked the US Supreme Court to allow construction of a 90,000-square-foot, $400-million White House ballroom, calling it "vitally required by national security". It's challenging a 2-1 ruling by the US Court of Appeals for the DC Circuit that blocked above-ground construction, citing the lack of congressional authorisation. Trump called the ruling a "national disgrace".
