On August 31, 2026, Supreme Court Chief Justice John Roberts expressed concerns about the legality of construction at the White House under President Donald Trump. He indicated that the $400 million ballroom project may be considered “likely unlawful” due to the absence of congressional approval.

The court’s 5-4 decision reversed a previous lower-court ruling that had temporarily stopped above-ground construction according to a report from Reuters. In his dissent, Roberts was supported by the three liberal justices.

The National Trust for Historic Preservation contested the project. They presented arguments addressing various construction elements. The court’s order did not conclude on the ballroom’s legality. It stated that construction could continue, given the ongoing legal battles. The administration contends that the ballroom is vital for security reasons and relies on private donations, not taxpayer funds.
