Judge Orders Halt to Trump’s $400M White House Ballroom Construction Without Congress

A federal judge in Washington ordered President Donald Trump’s administration to halt all aboveground construction on a planned $400 million White House ballroom, ruling that the project cannot proceed without explicit authorization from Congress and rejecting the White House’s attempt to rebrand the expansion as a national security imperative nytimes +1. Limited underground work on a new bunker and security facilities may continue while the legal fight moves to the appeals court nbcnews.

The order, issued Thursday by U.S. District Judge Richard J. Leon of the District of Columbia, tightened an earlier injunction that had paused most of the 90,000‑square‑foot East Wing addition but carved out an exception for safety and security work nytimes +1. Leon said the administration had “disingenuously” tried to exploit that exception by arguing the entire ballroom was essential to national defense, even as it acknowledged the project is largely funded by private donors and not scheduled for completion until 2028 nbcnews +1.

What the Judge Stopped — and What Can Still Be Built

Leon’s latest ruling bars any new aboveground construction related to the ballroom itself — including steel framing, exterior walls, and decorative elements — until Congress passes legislation specifically authorizing the project nytimes +1. The court held that presidents are custodians, not owners, of the White House and cannot unilaterally demolish and rebuild major components of the historic complex on this scale without a clear mandate from lawmakers bbc +1.

At the same time, the judge allowed certain underground work to proceed, including excavation and construction of a hardened bunker, utility corridors, and other security facilities deemed necessary by military and Secret Service officials, along with narrowly defined surface work needed to protect those structures from the elements nbcnews. Leon warned that “national security is not a blank check to proceed with otherwise unlawful activity,” underscoring that the security carve‑out could not be stretched to cover a 90,000‑square‑foot event space with 40‑foot ceilings nbcnews +1.

Donor Transparency, Historic Preservation, and a Political Flashpoint

The lawsuit was brought by the National Trust for Historic Preservation after the administration demolished the early‑20th‑century East Wing in October 2025 to clear the site for the ballroom bbc +1. The group argues that razing a major part of the White House to build what critics have called “a gilded edifice to one man’s ego” violated federal preservation laws and constitutional limits on executive control over federal property usatoday. The Trust hailed Leon’s ruling as a “significant victory” for safeguarding the White House as a public institution, not a personal venue bbc.

Ethics watchdogs have zeroed in on how the project is financed. The White House released a list it said includes 37 private donors, but a Citizens for Responsibility and Ethics in Washington analysis concluded that at least 23 contributors who lobby the federal government should have disclosed their ballroom donations in mandatory lobbying reports, and only one did so washingtonpost. The use of a nonprofit intermediary and the prospect of anonymous, multimillion‑dollar gifts tied to a presidential vanity project have fueled concerns about influence‑buying and conflicts of interest at the nation’s most symbolically important address washingtonpost. Trump has blasted the ruling as “a mockery to our Court System,” insisting the ballroom is “deeply important to our National Security” and vowing to appeal nbcnews +1.

The Bigger Picture

The clash over Trump’s ballroom has become a test case for the balance of power between Congress and the presidency on everything from historic preservation to national security and private money in public projects. With the administration already pursuing an appeal to the D.C. Circuit — and hinting at a potential trip to the Supreme Court — the fate of the ballroom now hinges not on architectural drawings or donor enthusiasm, but on whether federal courts are willing to let presidents radically reshape the White House without first asking Congress to sign off nytimes +2.
