The Trump administration moved Friday night to overturn a federal judge's order halting the $400 million White House ballroom project, warning in an emergency filing that leaving the half-built site exposed threatens national security and the safety of the president and his family.
Justice Department lawyers asked the U.S. Court of Appeals for the D.C. Circuit to stay U.S. District Judge Richard Leon's ruling, which found that construction on the East Wing replacement cannot proceed without congressional authorization. The administration's motion called the injunction "legally baseless" and argued that the president holds longstanding authority to improve White House grounds and structures without a separate act of Congress.
The filing landed just days after the National Capital Planning Commission voted 8-1 to approve the ballroom design, a vote that commission chair Will Scharf said was not affected by the judge's construction halt. The collision between a planning green light and a judicial red light has turned a building project into a constitutional test of presidential authority over the executive residence itself.
The emergency motion, reported by Fox News Digital, laid out the administration's core concern in blunt terms. Assistant Attorney General Brett Shumate wrote that the project already includes "deep Top Secret excavations, foundations, and structures" ready to receive fortified materials, steel, bulletproof glass, blast-proof glass, and drone-proof roofing, that must be installed quickly rather than left exposed to weather and outside observation.
Shumate framed the stakes plainly:
"Yet, a district judge ordered the President to halt ongoing reconstruction of the East Wing of the White House by April 14, leaving a massive excavation and structurally completed site adjacent to the now open and exposed Executive Mansion and threatening grave national-security harms to the White House, the President and his family, and the President's staff."
The National Park Service added its own filing, arguing that the federal district court lacks constitutional authority "to entertain this suit, which rests on a single pedestrian's subjective architectural feelings." The motion also contended that no member of the plaintiff organization, the National Trust for Historic Preservation, has legal standing to bring the case.
Breitbart reported that National Park Service lawyers went further in describing the security risk, arguing that "canvas tents, which are necessary without a ballroom, are significantly more vulnerable to missiles, drones, and other threats than a hardened national security facility." The project reportedly includes bomb shelters, military installations, and a medical facility alongside the ballroom itself.
Judge Leon's order came after the National Trust for Historic Preservation sued, alleging that the administration exceeded its authority when it razed the historic East Wing, originally built in 1902 and expanded during Franklin D. Roosevelt's presidency, and launched construction on the new 90,000-square-foot addition.
Leon found that the preservationist group was likely to succeed on the merits of its argument that Congress must authorize the project. As Newsmax reported, the judge wrote that the president is "not, however, the owner" of the White House and that no existing law gives unilateral authority to make such extensive changes.
That ruling reversed an earlier win for the administration. The Washington Times had reported that Leon initially rejected the preservationists' request to block the project, ruling at the time that the group was unlikely to succeed. The judge's later reversal, issuing the preliminary injunction, marked a sharp turn.
Leon did carve out an exception. His order allows work "necessary to ensure the safety and security of the White House and its grounds, including the ballroom construction site, and provide for the personal safety of the President and his staff." The administration's appeal seized on that exception, arguing it effectively concedes that the site cannot simply be abandoned mid-construction.
The broader pattern of legal clashes over executive authority gives this dispute added weight. The question of how far a single district judge can reach into the operations of the Executive Mansion touches separation-of-powers territory that goes well beyond ballroom architecture.
Shumate's filing emphasized the financial stakes. Nearly $400 million in private donations and contributions "have already been committed, or spent, in the purchase of heavy, large scale, and other types of building materials," he wrote. The motion stressed that no taxpayer dollars fund the project.
That funding model matters. Critics of the ballroom have focused on process, whether the project bypassed federal review and historic-preservation requirements. But the administration's argument flips the frame: this is a privately funded improvement to the nation's most important residence, authorized by a president exercising authority that predecessors used for more than a century without seeking a congressional vote.
The DOJ motion put the point sharply, arguing that the injunction could have been sought "long ago, prior to the start of construction," given that the project received "large scale media attention and publicity." Instead, the legal challenge arrived after excavation and structural work were already underway, a timeline the administration called unfair and dangerous.
President Trump weighed in Thursday night on Truth Social, celebrating the planning commission's 8-1 approval and noting that even Senator Rand Paul, whom Trump described as "known as an extraordinarily difficult vote", voted yes. Trump called the project "on time and under budget" and said it would become "the Greatest and Most Beautiful Ballroom of its kind anywhere in the World."
The commission vote and Trump's praise for Paul represented a rare moment of bipartisan-flavored cooperation on a project that has otherwise drawn sharp opposition from preservationists and their allies in the courts.
In a separate post this week, Trump took direct aim at the judge's reasoning:
"In the Ballroom case, the Judge said we have to get Congressional approval. He is WRONG! Congressional approval has never been given on anything, in these circumstances, big or small, having to do with construction at the White House."
Shumate echoed that argument in the formal filing, writing that "for decades, Congress has vested the President with overlapping statutory authorities that allow the President to make the improvements he deems necessary to White House grounds and structures." He also revealed that the judge had been invited to visit the construction site but "surprisingly, never responded to our invitation."
AP News reported that the 90,000-square-foot addition underwent recent design changes, including the removal of a large staircase and the addition of an uncovered porch. Renderings produced by McCrery Architects were shared by the White House, with Trump first posting an image of the proposed ballroom on Truth Social on February 3, 2025.
Commission chair Will Scharf told the commission he believes "in time this ballroom will be considered every bit as much of a national treasure as the other key components of the White House." He noted that the judge's ruling halts construction activity but does not stop the planning process, and that the order has been stayed for two weeks while the administration appeals.
That two-week window explains the urgency. The administration wants the D.C. Circuit to act before the April 14 deadline, when all non-security construction would have to stop under Leon's order. With foundations poured and structural work completed, halting now would leave sensitive infrastructure exposed, exactly the scenario the motion describes.
The New York Post reported that Trump argued construction can continue because the project includes security-related features such as bulletproof glass, protected doors and windows, drone-proofing, and secure air systems. Trump told reporters: "We have all of these things. So that's called, I'm allowed to continue building as necessary."
The ongoing clashes between the White House and its political opponents have become a defining feature of this administration. But this fight is different. It is not about immigration policy or election rules. It is about whether a federal judge can order the president to leave a hole in the ground next to the building where his family sleeps.
Several issues remain unresolved. The exact constitutional basis the National Park Service cited in challenging the district court's authority has not been fully detailed. The specific federal review requirements that preservationists say were bypassed have not been spelled out in public filings covered so far. And the D.C. Circuit has not indicated when it will rule on the emergency stay request.
The partisan dynamics around White House events and decisions will likely shape how Congress responds if the courts ultimately require legislative authorization. Whether enough members of both parties would vote to approve a project already under construction, and already paid for with private money, is anyone's guess.
What is not a guess is the physical reality on the ground. A massive excavation sits next to the Executive Mansion. Fortified materials are ready for installation. And a single judge has told the president of the United States to stop building on his own front lawn.
If a district court can halt a privately funded security upgrade to the White House over a preservationist's "subjective architectural feelings," the question isn't really about a ballroom. It's about who runs the executive branch.
