U.S. appeals court blocks Trump’s $400 million White House ballroom project

What This is

• The D.C. Circuit Court of Appeals upheld a court order pausing the White House ballroom project in a 2–1 decision.
• The court said Congress must explicitly authorize such a major construction project at the White House, rejecting the administration’s claim of enough existing authority to proceed.
• The ruling blocks above-ground construction but allows certain below-ground work tied to security, such as bunker-related work, to continue.
• The case was brought by the National Trust for Historic Preservation after the East Wing was demolished and construction began.
• Trump has said he will ask the Supreme Court to overturn the ruling and has argued the project is needed for safety and security at the White House.

Why This Matters

• It tests how far a president can go in reshaping federal property without lawmakers signing off.
• It affects who controls major building decisions at the White House: Congress that owns the purse strings, or the executive branch that runs the site day to day.
• It could set a practical precedent for using “security needs” to bypass normal oversight and public review for big construction projects.
• The Supreme Court appeal could change how quickly courts can pause a disputed federal project before the facts are fully tried.
