The claim lands in the middle of a high-stakes legal fight over the proposed White House ballroom. The key issue is not simply whether Congress has acted, but whether any action meets the legal standard identified by the appeals court.
Blanche said that Congress has already approved the White House ballroom project, pushing back on a federal appeals court ruling that ordered the Trump administration to halt construction unless it receives congressional authorization. The White House ballroom project has become a test of how far a president can go in remaking a historic federal property without a clearly identified act of Congress.
The claim matters because the U.S. Court of Appeals for the D.C. Circuit said on Aug. 7 that a massive new ballroom is a decision for Congress, not “Executive self-help.” Blanche’s position suggests the administration believes that approval requirement has already been met. The public record described in available reporting leaves the precise basis for that claim unclear.
The claim meets a court ruling
Blanche’s statement comes after a three-judge D.C. Circuit panel ruled 2-1 that construction on the ballroom must stop. The court gave the administration two weeks to seek relief from the Supreme Court, according to NPR’s account of the decision.

The legal dispute is not a routine argument over design preferences. It concerns whether the executive branch has authority to undertake a major construction project at the White House without explicit congressional authorization.
The court’s language was unusually direct: whether a large ballroom should be built is for Congress to decide. That makes Blanche’s assertion consequential. If Congress has already approved the project in a legally sufficient way, the administration could argue the court’s premise has been satisfied. If not, the project remains vulnerable even if officials describe it as necessary or desirable.
What “approved” could mean
In Washington, the word approved can cover several very different things. A member of Congress may publicly endorse an idea. A committee may advance a proposal. Congress may authorize a program, appropriate money, or pass a law that names a specific construction project.
Those are not automatically interchangeable, especially when a court is deciding whether an agency or administration has legal authority to alter a nationally significant federal site. The relevant question is likely to be narrower: what did Congress enact, what does that measure authorize, and does it apply to this ballroom and its construction?
Available reporting does identify one related congressional episode. Senate Republicans proposed $1 billion in taxpayer security funding connected to the ballroom in a broader immigration and border-security package in May, NPR reported. That provision was ultimately dropped after bipartisan backlash.
That history may explain why the administration and its critics could describe congressional involvement differently. But a proposed provision that did not survive the legislative process is not the same thing as an enacted authorization. Blanche has not, in the research supplied for this article, identified the specific law, appropriation or congressional action he believes already approved the ballroom.
A project far beyond a reception room
The proposed ballroom is not being discussed as a modest renovation. The administration has described a roughly 90,000-square-foot venue designed to seat 1,000 guests, NPR reported.
Cost estimates have also shifted sharply. The White House initially put the price at $200 million, while The Washington Post reported in June, citing contractor invoices, that costs could reach at least $600 million. Reuters described the project in its Aug. 7 report as a $400 million undertaking.
Those competing figures show why the authorization question has attracted such scrutiny. A project of that size would reshape the White House complex, require significant construction work and carry major fiscal implications even if private funding, security appropriations or other sources are involved.
The administration has also framed the work as a security project. President Trump has said the broader plan includes protective and military-related facilities, including bomb shelters, medical facilities, blast-resistant features and secure infrastructure. That argument treats the ballroom as part of an integrated security upgrade rather than a standalone event space.
Preservation groups see a limit
The National Trust for Historic Preservation sued the administration in December, seeking to stop work until required review procedures were completed, including congressional approval. The organization has maintained that only Congress can authorize a new ballroom at the White House.
Its argument is rooted in the White House’s status as both a working presidential residence and a historic public landmark. Preservation advocates say that changes of this scale require transparent review and a role for elected lawmakers, rather than a unilateral decision by the executive branch.
The administration has taken the opposite view. It has argued that the lawsuit lacks legal standing and that pausing the work would carry national-security consequences. Trump called the appeals court decision politically motivated and said the administration would appeal.
Both arguments reflect more than a disagreement over one building. The fight touches executive power, congressional control over federal property and spending, preservation law, and the level of public oversight required for changes to the nation’s most visible government residence.
The next test is documentation
Blanche’s claim does not by itself resolve the case. It raises the practical question that will matter in court and in Congress: can the administration point to a clear, enacted congressional authorization for this specific project?
There may be legal arguments over whether existing appropriations or statutes provide enough authority, whether security-related authority covers the entire development, and whether the ballroom can be separated from other claimed security work. Those distinctions could determine whether construction may resume.
For now, the most solidly established point is the conflict. Blanche says Congress has already approved the White House ballroom project. The D.C. Circuit recently concluded congressional approval is necessary for it to continue. Until the claimed authorization is publicly identified and tested, the debate is likely to remain focused on the gap between political assertion and legal authority.
