D.C. and Virginia sue to block Trump's 250-foot arch near Arlington cemetery

Washington, D.C., and Virginia sued the Trump administration on Saturday to block President Donald Trump's proposed 250-foot triumphal arch near Arlington National Cemetery. The suit comes days before construction could begin ¹.

The two jurisdictions call the project "flagrantly unlawful." They ask a federal court to halt construction and site preparation at Memorial Circle, the traffic circle between Arlington Memorial Bridge and the cemetery entrance ¹.

What the lawsuit claims

The complaint says the administration lacks the congressional approval required for the arch. It cites the Commemorative Works Act, which requires specific authorization from Congress for covered memorials ¹.

It also says the arch would break the Height of Buildings Act. The arch would rise 250 feet, and the suit says the law generally bars buildings over 130 feet on a business street or avenue in D.C. ¹.

The suit has eight counts. They include alleged violations of the Administrative Procedure Act, the National Environmental Policy Act and the National Historic Preservation Act. It names the National Park Service, the Interior Department, Interior Secretary Doug Burgum and Park Service official Jessica Bowron as defendants ¹.

Virginia Attorney General Jay Jones called the arch an "illegal vanity project" ¹. The White House has not answered the new suit in the copy we reviewed. In response to a separate suit earlier this month, a White House spokesperson said the administration had been "fastidiously compliant with all procedural and legal requirements" ¹.

The court should not allow this cynical gambit to succeed

Why D.C. and Virginia say they are harmed

The new suit argues the two jurisdictions would suffer real harm themselves. That matters because the Justice Department has argued in a separate case, brought by three Vietnam veterans and a preservationist, that those plaintiffs cannot show enough harm to sue ¹.

The Park Service has said construction would take two to three years and run 20 hours a day, according to the complaint. More than 27,000 vehicles, 1,100 bicyclists and 1,200 pedestrians use Memorial Circle each day, the filing says. Closing part of the circle could slow emergency crews moving between D.C. and Arlington County ¹.

The suit also points to Trump's September announcement that the arch would be a "Military Complex/Triumphal Arch" holding drones, snipers and ammunition. It says final planning documents never address those uses ¹.

The judge and the clock

On Friday, U.S. District Judge Tanya Chutkan questioned the government's national security argument. She said she would rule "expeditiously" on whether to halt construction ¹.

The arch is somehow going to deter assassination attempts on the president?

The National Capital Planning Commission is scheduled to consider final approval on Nov. 5. The administration has told the court work could start that same day if the Interior Department also signs off ¹.

Arlington County's board filed its own suit earlier this month. It says the Park Service failed to conduct a thorough review and is moving at a "feverish pace" ². The Interior Department said then that it continues to follow all laws and regulations ².

That matters because the states say that once ground is broken, the administration could argue that stopping work is too costly. The complaint says that as soon as defendants break ground, they will "inflict irreparable harm" on both ¹. These are allegations, and no court has yet ruled on the arch.
