Supreme Court allows White House ballroom construction to continue; Trump calls ruling 'horrendous, politically motivated, and unlawful'

The U.S. Supreme Court has allowed construction of President Trump's $400 million ballroom to continue, despite a lower court's ruling halting the project. Trump condemned the decision as 'horrendous, politically motivated, and unlawful,' while construction is reportedly 60% complete with 250 workers on site.

The U.S. Supreme Court's ruling allows President Trump's controversial $400 million ballroom project to proceed, despite a lower court's decision that halted construction due to concerns over historic preservation.

Chief Justice issued a stay, giving the administration time to appeal.

Earlier this month, the U.S. Court of Appeals ruled 2-1 in favor of the National Trust for Historic Preservation, stating that the decision to construct a massive ballroom should be made by Congress, not the Executive branch.

Trump criticized the ruling as 'horrendous, politically motivated, and unlawful,' claiming it jeopardizes national security.

The justices' decision allows underground construction related to national security to continue, while the ballroom project is reportedly 60% complete with 250 workers working 20-hour days.

The administration argues that halting the project now would be impractical, as costs for Trump's recent White House renovations, including the ballroom and a new helipad, have reached at least $900 million.

Key Insight
“The appeals court had ruled 2-1 that Congress must authorize the ballroom, not Executive self-help. The administration revealed 250 workers on 20-hour days with construction 60% complete, while total White House projects cost at least $900 million.”
