DOJ Asks Supreme Court to End White House Ballroom Block.

The National Trust for Historic Preservation asked the Supreme Court to pause Trump's White House ballroom project Tuesday, days after the administration filed its own emergency appeal to keep construction running.

• $400 million project covers 90,000 square feet and includes demolition of the East Wing.
• 65% of construction is complete, the administration told the court.
• Above-ground work stops August 21 unless the Supreme Court intervenes.
• The lower-court injunction exempts underground security and bunker construction.

Why it matters: The core legal dispute is whether the project can proceed without explicit congressional authorization. If the Supreme Court does not intervene before Friday, above-ground work halts and the administration says the open construction site itself creates a security risk.

• The trust warns that materials designed to withstand nuclear blasts make the structure essentially impossible to alter once complete.
• Construction is expected to finish a few months before Trump's term ends if allowed to continue uninterrupted.

How 20 sources split on this story

Where they split: The central dispute is whether the president holds unilateral authority to renovate the White House without congressional approval, or whether federal law requires it.

What’s next: The Supreme Court must decide whether to grant, deny, or hold the administration's stay request before Friday.

• Solicitor General D. John Sauer asked the court to rule before the appeals panel's decision takes effect.
• Will Chief Justice Roberts act alone or refer the application to the full court before the Friday deadline?
• If construction is halted, what are the actual security consequences the administration warns of?
• Will the court address the standing question — whether the trust has the legal right to sue — before ruling on the stay?
