Vietnam veterans asked a federal judge to block work on President Trump’s planned 250-foot arch near Arlington National Cemetery unless Congress first authorizes it, after the Justice Department said construction could begin Nov. 5.
The request for a preliminary injunction came a day after the Justice Department told the court that work on the arch could start on Nov. 5, immediately after the National Capital Planning Commission is set to grant final approval.
ABC News reported that Vietnam-era veterans already suing over the project want Judge Tanya Chutkan to stop construction unless lawmakers sign off. The government notice tracks an earlier order requiring at least 14 days’ warning before work begins.
The planned arch would rise in a traffic circle across the Potomac River from the Lincoln Memorial, at the foot of Arlington National Cemetery. The Trump administration is moving the project through site work, design, and capital planning reviews while opponents press a core claim: only Congress can green-light it.
The challengers are not abstract interest groups. Fox News reported the plaintiffs as Vietnam veterans Michael Lemmon, Shaun Byrnes, and Jon Gundersen, joined by architectural historian Calder Loth.
Their lawyer, Nicolas Sansone of Public Citizen Litigation Group, tied the case to the cemetery itself.
"Our plaintiffs are three Vietnam veterans and an architectural historian. All of them have a deep personal relationship with Arlington National Cemetery."
The Washington Examiner said the suit was filed in U.S. District Court for the District of Columbia and aims to halt the Independence Arch planned between the Lincoln Memorial and Arlington National Cemetery. The filing alleges the monument needs direct legislative approval from Congress.
In court papers, the veterans asked Chutkan to intervene so the administration cannot lock in the build before a final ruling on legality.
"render the arch a fait accompli before this Court has made a final determination whether Defendants' project is unlawful."
They also accuse the administration of pushing the project without the approval they say the law requires.
"failed to obtain (or even to seek) approval from the one body that, by law, must authorize the project: Congress."
The Trump administration’s answer rests on history, not a new statute. Officials argue a 1925 bill signed by President Calvin Coolidge, the law that provided for construction of Memorial Bridge, also authorizes the arch because the initial plan called for columns at the end of the bridge.
Opponents reject that reading. They call the administration’s theory “entirely untethered” from the text of the 1925 law. Sansone framed the gap in practical terms: a century-old authorization for a different project, under a defunct commission and a different price cap, cannot stretch to cover a larger, separate monument today.
"Congress's authorization to have a particular project built at a particular time subject to a specific price cap by a now-disbanded commission can't reasonably be relied on to authorize a totally different independent project that's going to cost way more money centuries into the future."
That dispute is the heart of the case. One side says existing law already covers the work. The other says Congress must vote again before a single shovel turns.
Chutkan had already ordered the government to give at least 14 days’ notice before starting work on the arch. The Justice Department’s Wednesday notice fits that window and points to Nov. 5 as the date construction could begin, right after the National Capital Planning Commission’s expected final approval.
The veterans’ filing describes the run-up as aggressive groundwork, site testing, architectural plans, and commission approvals, while still skipping what they call the required step on Capitol Hill. Their papers put it this way:
"barreled ahead, doing site testing, drawing architectural plans, and seeking approvals from commissions populated by friends of the administration."
Those are the plaintiffs’ words, not a court finding. The administration has treated the planning path as lawful under the older Memorial Bridge authority and has kept the judge informed on timing.
Beyond the statute fight, the challengers argue the 250-foot arch would disrupt historic sightlines veterans prize, views linking the Lincoln Memorial, Arlington National Cemetery, and Arlington House. Fox News coverage of the case stressed that claim as central to why these particular plaintiffs sued.
In September, the administration itself acknowledged the arch would cause “adverse effects” on the setting and views along the river. Officials said the impacts “cannot be fully avoided” because the location is “central to the undertaking.” The National Park Service has also recognized unavoidable adverse effects on historic properties, according to the same reporting on the lawsuit.
Related planning steps have moved in parallel. The Interior Department has submitted final plans to the National Capital Planning Commission. A federal preservation agency has been described in coverage as ending required consultation with local officials on the arch. None of that resolves the congressional-authorization question now before Chutkan.
A preliminary injunction is a temporary brake. The veterans want construction frozen unless Congress acts. The government has signaled it is ready to break ground on Nov. 5 if final capital-planning approval lands as expected.
The judge already forced a notice period. The new filing asks her to go further and halt the project on the claim that the 1925 bridge law does not reach a modern triumphal arch of this size and scope.
No ruling is in yet. The record shows a live collision among executive-branch planning, a century-old statute, cemetery-adjacent design fights, and a federal judge who has already supervised the start-of-work timeline.
If the law already authorizes the arch, the build should proceed under that authority. If it does not, Congress can say so in the open, not through a last-minute freeze that treats every memorial as endless litigation.
