Washington, D.C., and the commonwealth of Virginia filed a joint lawsuit Saturday to block construction of President Donald Trump’s planned monumental arch near Arlington National Cemetery. The legal challenge targets the National Park Service and the Department of the Interior, asserting that federal officials have rushed forward with an illegal project designed to bypass judicial review.
The proposed structure is a 250-foot triumphal arch intended for a site near the entrance of Arlington National Cemetery. President Trump has stated that the construction will celebrate the nation’s 250th birthday and function as a munitions depository. Excavation work at the site commenced in early September.
In their legal filing, the two jurisdictions contend that the project is flagrantly unlawful and will permanently alter the landscape of the nation’s capital. The lawsuit states that federal defendants have made only half-hearted gestures toward complying with environmental and planning requirements, adding that officials appear to be attempting to outrun judicial scrutiny by rapidly breaking ground.
“It is entirely foreseeable that, once construction begins, Defendants will argue — as they have done in other cases — that an order halting construction would irreparably harm the federal government, pose security risks and impermissibly alter the status quo they have unilaterally created,” the complaint alleges. The plaintiffs maintain they possess indisputable standing to bring the action.
D.C. Attorney General Brian Schwalb, a Democrat, stated that the arch would cause serious, immediate, and irreparable harm to the District and its residents. Virginia Attorney General Jay Jones, also a Democrat, criticized the initiative as an illegal vanity project that would disrespect the cemetery and the sacrifices it represents.
“The Commonwealth has a solemn duty and a profound interest in preserving the dignity of this sacred place,” Jones said in a statement, vowing to vigorously litigate to protect its sanctity and honor fallen service members.
The lawsuit outlines multiple legal violations, arguing that the arch has not been authorized by Congress and that the National Park Service failed to conduct appropriate consultations required before transforming the capital’s physical landscape and historic plan. Furthermore, the plaintiffs argue the structure violates the Height of Buildings Act of 1910, which caps capital structures at 130 feet, making the 250-foot arch nearly double the legal limit. Additional concerns raised in the complaint include potential degradation of regional security, compromised emergency preparedness, traffic disruption, and environmental damage.
The new action compounds existing legal challenges facing the development. Arlington County has previously filed a separate lawsuit, and two Vietnam War veterans joined with a historian to launch another legal challenge. U.S. District Judge Tanya Chutkan heard arguments in the veterans’ case on Friday, expressing initial skepticism toward the federal government’s arguments while noting that the veterans’ legal standing remains murky and subject to judicial review over the weekend.
