Virginia and D.C. sue to stop proposed Trump arch

The Trump administration has said it plans to begin construction of the arch next week.Andrew Harnik / GettyShareAdd NBC News to GoogleOct. 31, 2026, 1:03 PM EDTBy Gary Grumbach and Alexandra MarquezVirginia and the District of Columbia filed a lawsuit in federal court Saturday in a last-ditch effort to stop the construction of the triumphal arch planned for Memorial Circle in Washington.

The Trump administration has said it plans to begin construction of the arch next week, on Nov. 5.

“The construction of the Arch will inflict immediate and irreparable harm on the District and Virginia,” Virginia Attorney General Jay Jones and D.C. Attorney General Brian Schwalb wrote in the lawsuit. “The Arch is slated to be built on a busy traffic circle that abuts the border between the jurisdictions, at the center of a historic viewshed, in a river whose environment the District has a statutory responsibility to protect.”

“Both the construction of the Arch and the completed monument will disrupt the operations of both jurisdictions, impair their ability to carry out their responsibilities under federal and local law, and require the expenditure of substantial resources to mitigate and address those impacts,” they added.

The attorneys general wrote that their request to block construction is urgent.

Jones and Schwalb added that they believe the administration is violating the Commemorative Works Act by bypassing specific congressional authorization and violating the Height of Buildings Act by constructing an arch that’s set to exceed 130 feet in height. They also alleged violations of the National Environmental Policy Act and the National Historic Preservation Act.

The commission is set to vote on final plans for the arch on Nov. 5.

Renderings obtained by NBC News in April show that the arch is slated to feature winged eagles, Lady Liberty and a line from the Pledge of Allegiance.

In September, the president said on Truth Social that the arch would also serve a national security function because it will be outfitted to “house, store, and have the rapid ability to use large numbers of drones, plus Snipers, on both the roof and plaza areas, and additionally have and hold large quantities of sniper ammunition in storage.”

But final plans and renderings submitted to the NCPC do not include the military upgrades the president wrote about.

Trump has used national security as an argument in favor of other construction projects that have faced legal battles, like the new ballroom he is building at the White House. In addition to functioning as a gathering space for large events at the White House, the president has said, the addition will also house a military complex to be built underneath the ballroom.

“When completed in the Summer of 2028, the magnificent Ballroom and Military Complex will be something that the entire Country is very proud of,” the president wrote in an August Truth Social post after the Supreme Court allowed construction of the ballroom to continue, rebuffing a legal challenge from the National Trust for Historic Preservation.

The president has also drawn the ire of locals with a proposed plan to renovate the East Potomac Golf Links course in Washington, despite legal hurdles with that project.

In a post on Truth Social Thursday, Trump said why he favored renovating the golf course.

“East Potomac Golf Course is highly dangerous, dilapidated, and absolutely disgusting. Below are new photos of the deplorable conditions of the driving range building, including excrement in the stairwell. The gaping holes in the driving range’s ‘protective’ netting are highly hazardous. Golf balls soar through the holes at high speed and hit unexpecting Golfers — including a White House staffer who was, sadly, hit violently in the chest,” the president wrote.

He has promised to turn the course into “a World Class Championship Golf Course.”
