White House ballroom construction hit a major legal wall Friday after a federal appeals court ruled that Donald Trump cannot move forward with the massive project above ground without authorization from Congress. According to the Associated Press, the ruling stops work on the privately financed $400 million ballroom while reinforcing a much bigger point at the center of the case: private money does not necessarily give the executive branch a free pass to reshape federal property.
The August 7 decision came from a three judge panel of the U.S. Court of Appeals for the District of Columbia Circuit. The court’s published opinion shows Judges Patricia Millett and Bradley Garcia formed the majority, while Judge Neomi Rao dissented. AP reports that the panel ruled 2 to 1 in favor of the National Trust for Historic Preservation, which sued after the East Wing was demolished in 2025 to make room for the project.
The majority made clear that its ruling was about who has the legal authority to approve such a project, not whether a ballroom would be useful or attractive.
“Whether or not a massive ballroom should be constructed is for Congress to decide and is not a matter for Executive self-help,” the court wrote.
“This holding has nothing at all to do with whether the proposed ballroom is desirable, or not, as a matter of policy. This ruling does not even necessarily mean that the Defendants may not ultimately construct the ballroom.
“What it does mean,” the court continued, “is that the Defendants may not do so during the district court’s expeditious litigation without securing Congress’s authorization, as the Constitution and laws require.”
According to AP, the White House ballroom ruling will not take effect immediately. The appeals court stayed its decision for 14 days, giving the Trump administration time to seek relief from the U.S. Supreme Court. That leaves open the possibility that the legal fight could move quickly to the nation’s highest court before the construction dispute is settled.
Trump has repeatedly argued that congressional approval should not be necessary because taxpayer money is not funding the ballroom. AP reports that Trump has said corporations, wealthy individuals and Trump himself are financing the construction.
“He’s saying I need congressional approval and he’s so wrong,” Trump said in March following an earlier ruling from U.S. District Judge Richard Leon. “This is being financed privately.”
But the appeals court’s decision separates the question of who pays for the project from the question of who has authority over federal property. According to the court opinion, the legal dispute centers in part on Congress’s constitutional power concerning property belonging to the United States, including the White House complex.
The White House ballroom project is substantial by any measure. According to AP, plans call for a roughly 90,000 square foot ballroom at the site where the East Wing previously stood, and Trump has said the completed space would hold 999 people. The outlet reports that the project represents the largest structural change to the White House in more than 70 years.
That history gives the dispute another layer beyond the courtroom. According to the White House Historical Association, the modern East Wing traces its history through several major changes. Theodore Roosevelt ordered construction of East and West Wings in 1902, and Franklin D. Roosevelt expanded the East Wing in 1942, adding a second story as well as additional office and support space. The association also notes that security infrastructure was historically tied to that expansion, including a wartime shelter beneath the wing.
Security has become a central argument in the current White House ballroom case too. According to AP, government attorneys told the courts that the broader construction project includes defenses and facilities intended to address threats including drones, ballistic missiles and biological hazards.
“These upgrades, alterations, and improvements are essential to protecting the President, his family, and his staff, as well as the White House itself, and the entire project flows from them,” government attorneys wrote in a court filing.
Attorneys representing the National Trust rejected the idea that stopping the ballroom itself would create the kind of security emergency the administration described.
“That commonsense conclusion is not clearly erroneous, and there is no basis to disturb it,” they wrote.
The courts have drawn an important distinction between the ballroom structure and work taking place underneath the property. According to AP, Judge Leon’s April order blocked above ground construction while allowing work involving bunkers and other national security facilities below ground to continue. The appeals court has now upheld that restriction.
Trump sharply criticized Leon after the district court ruling, according to AP, calling him a “Trump Hating” judge who “has gone out of his way to undermine National Security, and to make sure that this Great Gift to America gets delayed, or doesn’t get built.”
The White House ballroom had already cleared another major federal review before Friday’s appeals court decision. According to the National Capital Planning Commission, the commission voted on April 2 to approve preliminary and final site and building plans for what officials formally call the East Wing Modernization Project. The commission described the development as a permanent and secure event space intended to increase capacity for official state functions.
That planning approval, however, did not end the separate fight over congressional authority.
The National Trust for Historic Preservation celebrated Friday’s ruling. In an official statement, organization president and CEO Brent Leggs said the decision protected the public’s role in decisions surrounding historic federal property.
“From the beginning, our position has been clear and consistent: the law states that only Congress can authorize the construction of a ballroom at the White House,” Leggs said. “We are pleased with the DC Circuit Court’s decision to uphold the District Court’s preliminary injunction, which although stayed for 14 days will block any above-ground ballroom construction unless and until Congress takes action.”
The White House ballroom fight now carries implications well beyond one construction project. Based on the appeals court’s ruling, the immediate question is whether the Trump administration will persuade the Supreme Court to intervene. The larger question is whether private financing can change the constitutional limits governing major alterations to property that belongs to the federal government. For now, two federal courts have answered that question the same way: when it comes to building the ballroom above ground, Congress still has a say.
