US judge pushes back on Trump arch ‘national security’ argument

On October 30, 2026, U.S. District Judge Tanya Chutkan questioned the government's national security claims for President Donald Trump’s proposed 76-meter (approximately 250-foot) triumphal arch in Washington, D.C., which is modeled after the Arc de Triomphe in Paris. Top officials from Trump’s administration had previously stated that the arch would serve as a "top-grade military complex," housing drones and snipers to protect against enemy drones. However, Judge Chutkan noted that this was the first time national security arguments were raised for the project.

The lawsuit challenging the construction of the arch is brought by a group of Vietnam War veterans who argue it lacks proper congressional approval and has been rushed through without adequate review. The Justice Department contends that the monument serves as a critical infrastructure node for drone detection and mitigation. Despite these claims, Judge Chutkan expressed skepticism about invoking national security to expedite construction.

Construction on the arch could begin as soon as November 5 if the National Capital Planning Commission issues final approval, according to court filings by the Justice Department. The plaintiffs argue that public interest leans against allowing the project to proceed so quickly and are seeking a preliminary injunction to halt it before any significant steps towards construction occur.
