A judge blocked efforts to stop the Trump administration’s $400 million White House ballroom project, allowing demolition of the historic East Wing to proceed.

A federal judge has denied a request to halt the Trump administration’s $400 million White House ballroom project, which involves demolishing the historic East Wing. The National Trust for Historic Preservation sued, arguing the project violated federal law by proceeding without congressional approval, environmental review, or required federal agency consultations. Judge Richard Leon ruled the group failed to meet the high standard for a preliminary injunction, citing insufficient legal grounds and noting the White House office overseeing the project is not subject to the Administrative Procedure Act. The ballroom, planned at 90,000 square feet and funded by private donations, will replace the East Wing, which housed the first lady’s offices and a theater. Above-ground construction is expected to begin in April 2026, with no final completion date set. The ruling allows the project to move forward, though the preservationists may amend their lawsuit.
