Donald Trump says planned triumphal arch near Arlington will be "the greatest of them all"

President Donald Trump said a proposed 250-foot triumphal arch near Arlington National Cemetery would also have a military role involving drones and snipers, with both usable from its roof and plaza. He described the change in a Sept. 20 Truth Social post as made at the military's request for national security. The arch, part of efforts to beautify Washington and mark the 250th anniversary of American independence, would stand on Columbia Island at Arlington Memorial Bridge's western end, inspired by Paris's Arc de Triomphe. The U.S. Commission of Fine Arts has given approval; the National Park Service backs the project while cautioning it could disrupt views among monuments. A planning commission granted preliminary approval while flagging issues for final review. Veterans and a historian sued, saying Congress must authorize construction; the administration cites a 1925 statute.
