Drone tracked near Air Force One as Trump defends $400M White House ballroom

An unidentified unmanned aerial vehicle was tracked near Air Force One while President Trump was aboard. On the plane, Trump defended a planned $400 million White House ballroom, saying a massive military complex will be built beneath it. The ballroom is a top administration priority and faces a critical congressional vote and a possible federal court halt. The drone episode raises national security concerns about presidential aircraft vulnerability, and the ballroom fight matters because it involves large federal spending and potential military construction at the White House.
