The Trump administration has returned to the US Supreme Court over the White House ballroom, asking the justices to end the legal challenge to the project outright. In a petition filed on 5 November, Solicitor General D. John Sauer asked the court either to summarily reverse a district judge's order halting above-ground construction on the site of the demolished East Wing, or to take the case up for full review.

The case began when the National Trust for Historic Preservation sued in December 2025, arguing the project could not proceed until the National Capital Planning Commission and the Commission of Fine Arts had reviewed the plans and Congress had authorised the construction. Work had begun in October 2025, and demolition of the East Wing was completed that December. In March 2026 a federal judge issued a preliminary order barring above-ground work while allowing below-ground construction and safety-related activity. The administration argues the project is a national-security necessity, combining a ballroom above with hardened facilities below, and should proceed free of what it calls judicial superintendence.

The Supreme Court has already weighed in once, voting five to four on 31 August to put the injunction on hold while the government sought further review, so construction has continued in the meantime. The ballroom is planned at roughly 90,000 square feet, substantially larger than the White House's 55,000-square-foot Executive Mansion, at a cost of at least $400 million, and is reportedly around seventy percent complete. The Trust's response to the new petition is due on 7 December. The renewed push comes days after Republicans suffered sweeping losses in nationwide elections, with the president touring the construction site on 4 November and describing the ballroom as a special structure.
