DC and Virginia Sue to Stop Trump Admin’s Triumphal Arch Construction

The District of Columbia and the Commonwealth of Virginia have jointly filed a lawsuit to prevent the Trump administration from constructing a proposed 250-foot-tall triumphal arch. Filed on Saturday, October 31, 2026, the legal action contends that the project is "flagrantly unlawful," lacks congressional authorization, and violates the District's building height restrictions, which cap structures at 130 feet. The administration reportedly intends to commence construction as early as the following week.

Attorneys General Brian Schwalb of D.C. and Jay Jones of Virginia assert that the arch, planned near Arlington National Cemetery, would inflict "serious, immediate and irreparable harm" on the region. Their complaint highlights concerns that the multi-year construction would severely disrupt traffic, especially impacting emergency services, pollute the Potomac River, and compromise the solemnity of Arlington National Cemetery. The lawsuit also argues that the Trump administration has not adequately adhered to mandatory review processes for such an ambitious undertaking.

This recent lawsuit adds to growing legal challenges against the triumphal arch, which the Trump administration initially proposed to commemorate the nation's 250th birthday, later suggesting it could also serve national security purposes. A separate federal judge, Tanya S. Chutkan, is already weighing an injunction in another case brought by Vietnam War veterans and a historic preservationist, having expressed skepticism regarding the administration's haste to begin construction.
