Federal judge reinforces order halting Trump's 250-foot triumphal arch
U.S. District Judge Tanya Chutkan reinforced an order requiring the Trump administration to give 48 hours' notice before conducting work at the site of a proposed 250-foot triumphal arch near Arlington National Cemetery. The ruling followed Interior Secretary Doug Burgum's announcement of plans to break ground. While the administration argues its immediate plans to dig test pits starting September 21, 2026, are standard archaeological surveys, veterans and historians suing to block the project argue it lacks congressional approval and violates height limits.
