Supreme Court Asked to Halt or Continue White House Ballroom Construction

The Trump administration is asking the Supreme Court to allow construction on the White House ballroom project to continue during the appeals process. The National Trust for Historic Preservation is asking the justices to suspend construction while the litigation continues.

A divided D.C. Circuit ruling ordered aboveground construction, including East Wing renovations, to stop on Friday, August 21, 2026. The administration sought emergency Supreme Court relief before that date, and the ruling was suspended while the appeal proceeded.

The Guardian reports that the project is estimated to cost $400 million and cover 90,000 square feet. The reported construction has included demolition of the White House East Wing. The administration says the work has been underway for 10 months and is approximately 65 percent complete.

The National Trust alleges that the administration accelerated construction while the appellate court considered the case. The group’s reported Supreme Court filing said a 250-person crew worked 20 hours a day, seven days a week. The Trust said the effort was intended to put the ballroom beyond judicial intervention. Those are allegations from the preservation group’s filing, not independently verified construction records or judicial findings.

The National Trust says the lower-court injunction allows continued work on an underground military facility and activity needed to protect the president, his family, staff, and the White House complex. Solicitor General D. John Sauer describes the project as an integrated military complex with a secure ballroom that is vitally required by national security. The Justice Department argues that the open construction site makes the White House harder to protect.

The parties present competing legal positions. The National Trust argues that Congress must authorize construction on federal property, while the administration argues that the president has unimpeded authority to renovate the White House. District Judge Richard Leon wrote that “no statute comes close to giving the president the authority he claims to have.”

The reported construction progress and the Trust’s acceleration allegation support an inference that continued work could make later judicial relief more costly, disruptive, or practically ineffective. That is not a final determination that the project is unlawful, and the supplied reports do not establish that completed work is irreversible. The supplied records also do not identify the project’s private financiers, contractors, subcontractors, procurement arrangements, or ultimate financial beneficiaries, nor do they establish congressional authorization or a final merits ruling against the administration.
