The Justice Department moved to pressure the National Trust for Historic Preservation to drop its lawsuit challenging President Donald Trump’s planned $400 million White House ballroom. Acting Attorney General Todd Blanche said the government would seek dismissal after an “extraordinary” event at the White House Correspondents’ Dinner, arguing the Washington Hilton was demonstrably unsafe for events involving the president. The DOJ’s letter requested dismissal by 9 a.m. Monday, framing the ballroom project as a long-term safety and security upgrade. The preservation group said it would review the filing with legal counsel after a court challenge filed in December, following demolition work tied to the project. The dispute matters beyond federal courts: it signals how security incidents are being used to shape contested public spending and compliance timelines—issues that university general counsels and compliance offices can track when similar risk-and-oversight questions arise in campus construction and safety litigation.
