Judge Tanya Chutkan Halts Construction of Trump Arch After Commission Vote

District Court Judge Tanya Chutkan issued an order just before midnight on Thursday that bars the federal government from starting construction on President Trump's proposed arch. The injunction stops work for 14 days and halts the administration's plan to begin excavation immediately following its approval by the National Capital Planning Commission.

The commission voted 8-4 to grant final approval for the 250-foot structure in Memorial Circle, the traffic island connecting the Lincoln Memorial to Arlington National Cemetery. The vote concluded after nearly nine hours of virtual testimony from 131 speakers, including veterans, lawmakers, and preservation experts. Trump administration officials have stated that construction would occur 20 hours a day for two to three years.

In a 33-page opinion, Chutkan criticized the administration's shifting justifications for the project, particularly its late emphasis on national security. She agreed with the governments of the District of Columbia and Virginia that the arch would cause immediate logistical and financial harm. "The threatened harms will materialize as soon as construction begins, in part because the traffic disruptions will occur immediately," Chutkan wrote.

The legal challenge stems from two lawsuits consolidated by Chutkan. A group of Vietnam War veterans and an architectural historian sued earlier this year, arguing the arch requires Congressional approval, which the administration has not sought. The Democratic governments of D.C. and Virginia filed a similar suit last weekend. Chutkan asked the government to notify the court within an hour of the commission's decision, leading to the rapid judicial response.

During the commission meeting, Vice Chair Stuart Levenbach noted that the project proponent was under a time constraint and wanted a decision that day. D.C. Council Chair Phil Mendelson argued that final site and building plans were missing. He introduced a motion to postpone the vote until early December, but the measure failed by a vote of 8 to 4.

Supporters of the arch, including Trump-appointed Chair Mark Paoletta, dismissed concerns about height restrictions and environmental laws. They cited a 1925 authorization for unbuilt columns on the same site and recent claims by Defense Secretary Pete Hegseth that the monument would enhance national security. Interior Department official Greg Wischer acknowledged that specific national security functions were filed under seal in court, but the National Park Service had not been privy to those details.

Critics reacted swiftly to the commission's approval. Brent Leggs, president of the National Trust for Historic Preservation, called the vote a sham that violated federal statute. Virginia Representative Don Beyer, who introduced a bill to prohibit and defund the arch, said the number of co-sponsors for the measure is expected to grow from 80 to at least 200 in the new year. Representative Jared Huffman warned officials that advancing a project not authorized by Congress places them at legal risk.

The administration had previously told the court it could begin excavation on the day of the vote despite the pending legal challenges. White paint marking construction lines had been placed on the grass in Memorial Circle on Saturday by the designated construction firm. The administration notified the court of the commission's approval within half an hour of the vote, prompting Chutkan's order before the weekend.
