Washington: DC and Virginia sue together to block Trump's 250-foot triumphal arch before November 5 groundbreaking

Washington, DC and Virginia sued together in federal court on Saturday, October 31, seeking to block President Donald Trump's proposed triumphal arch. The 250-foot (76-metre) memorial arch would stand on a patch of grass at the end of the bridge spanning the Potomac River, connecting the District with Arlington National Cemetery, on the border between DC and Virginia; the administration says construction could begin as early as November 5.

Two attorneys general: no congressional authorisation, 'flagrantly unlawful'

The plaintiffs are DC Attorney General Brian Schwalb and Virginia Attorney General Jay Jones, suing the National Park Service and the Interior Department. Their filing argues the project is unlawful because Congress never authorised it, and that it breaches the DC Height of Buildings Act and other historic-preservation laws, calling it 'flagrantly unlawful'; the two jurisdictions warn that as soon as the government breaks ground, it will inflict 'serious, immediate and irreparable harm' on both. The filing also notes the arch site sits at the centre of a major traffic artery between the District and Virginia, where any construction disruption could affect emergency responses that the two jurisdictions routinely handle jointly.

Third lawsuit: judge has questioned the 'national security' case, no ruling yet

This is the third lawsuit against the arch. Arlington County sued in early October, and three Vietnam War veterans and an architectural historian have also sued. US District Judge Tanya Chutkan, who is considering the earlier case, held an emergency hearing on October 30 and questioned the administration's argument that the arch is needed for national security and anti-drone defence in order to break ground as early as November 5; she did not rule immediately but said she would move expeditiously. The administration has submitted a 106-page plan for the arch and plans to seek final approval at a meeting of the National Capital Planning Commission.

Background and what happens next

The arch is modelled on triumphal arches in other cities, including Paris's Arc de Triomphe, and the plan submitted by the government envisions a structure more than 12 storeys high topped by a huge bronze statue of a winged Lady Liberty carrying a torch. Opponents argue the project cannot lawfully proceed without congressional authorisation; the administration hopes to secure final approval around November 5. With a third lawsuit now filed, whether that timetable holds will depend on whether a court issues an order halting the work.
