A joint federal lawsuit argues the planned 250-foot monument off the Potomac River bypasses Congress and threatens regional traffic and emergency services.
The District of Columbia and Virginia filed a joint federal lawsuit Saturday to halt the construction of President Donald Trump’s proposed memorial arch, arguing the project would cause immediate disruption to regional infrastructure and bypasses required federal approvals.
The legal filing comes as the Trump administration prepares to seek final approval from the National Capital Planning Commission on Nov. 5, with officials indicating ground could be broken that same day. The planned 250-foot triumphal arch would sit at Memorial Circle on a strip of land off the bridge across the Potomac River that links Washington with Arlington National Cemetery. That height would make the monument 100 feet taller than the Statue of Liberty measured from its base to the torch tip.
Why the jurisdictions filed suit
In the complaint, D.C. Attorney General Brian Schwalb and Virginia Attorney General Jay Jones asked a federal judge for a temporary restraining order to block any imminent construction work, CBS News reported. The attorneys general argued that “as soon as Defendants break ground on this project, they will inflict irreparable harm on both the District and Virginia.”
The lawsuit contends that the anticipated three-year construction effort would snarl traffic along a vital transit artery between Virginia and the capital, pollute the Potomac River with stormwater runoff, and impede regional emergency response operations. The complaint specifically cited the need for smooth cross-border coordination during major crises, noting the January 2025 midair collision between a military helicopter and a commercial airliner that killed 67 people.
The two jurisdictions also accused the administration of evading several federal statutes, according to NBC News. The filing asserts that the federal government is flouting the Commemorative Works Act by moving forward without explicit authorization from Congress. In addition, the attorneys general alleged violations of the National Environmental Policy Act, the National Historic Preservation Act, and the local Height of Buildings Act, which restricts structures exceeding 130 feet.
The lawsuit warned that if work starts, the administration will claim that judicial intervention harms the federal government or creates national security liabilities. The complaint urged the judge to act quickly, stating, “The Court should not allow this cynical gambit to succeed.”
Details of the 12-story monument
The administration unveiled a 106-page submission on Friday laying out technical plans for the arch. The proposal describes a 12-story structure topped by an occupied roof and an observation deck offering panoramic views to the east and west. It includes two interior mezzanines, office space, program areas, a staff lounge, elevators, spiral staircases, and a dedicated fire command center.
Artistic elements include a winged bronze depiction of Lady Liberty bearing a torch with an eternal flame, alongside winged eagles and a quote from the Pledge of Allegiance. White House spokesman Davis Ingle told CBS News that the arch would become a global landmark honoring fallen service members and veterans throughout American history, praising Trump’s focus on national monuments.
While Trump previously claimed on Truth Social that the structure would double as a military facility housing snipers and drone fleets, the final blueprints submitted to planners did not include those specific military installations. Trump has made similar defense arguments for other capital initiatives, such as his ongoing Trump plans D.C. golf course overhaul at East Potomac Golf Links and a White House ballroom project that survived an earlier challenge at the Supreme Court.
Mounting legal challenges and what happens next
Saturday’s action marks the third active lawsuit seeking to derail the arch, Al Jazeera reported. A group of three Vietnam War veterans and an architectural historian brought the initial challenge in February, arguing the structure would obscure views of Arlington National Cemetery. Arlington County’s governing board filed a separate suit on Oct. 8, warning of residential harm and disruptions to local flight corridors.
U.S. District Judge Tanya Chutkan is overseeing the veterans’ case. Following a court hearing on Friday, Chutkan said she would rule expeditiously on a request for a preliminary injunction. She had already directed the federal government to provide 48 hours of advance notice before beginning any on-site construction.
The National Capital Planning Commission, whose initial review passed earlier this year under Trump appointees, is scheduled to take its final vote on the plans on Thursday, according to PBS NewsHour. That vote will determine whether the administration attempts to break ground immediately or waits for rulings from the federal bench.
