Judge Leon Blocks Trump Ballroom Build, Allows Underground Security Work
A federal judge has drawn a new line on Donald Trump’s White House ballroom project, allowing some construction to continue while blocking the rest.
The ruling matters now because it splits the project in two—raising fresh legal questions about presidential authority and national security claims.
According to the Associated Press, U.S. District Judge Richard Leon said above-ground construction on the $400 million ballroom cannot proceed without congressional approval, but underground work tied to security can continue.
That includes excavation and building bunkers, medical facilities, and military installations beneath the site.
The complication is whether those underground elements can truly be separated from the ballroom itself, a point both sides are still fighting over.

“The defendants’ claim that the entire project qualifies for a security exception is not correct,” Leon wrote.
The dispute centers on whether the administration stretched “national security” to justify a major structural expansion of the White House.
The National Trust for Historic Preservation argues the ballroom is unnecessary and unlawful without Congress, while government lawyers insist stopping construction could expose the site to risks from drones, missiles, and other threats.
An appeals court recently ordered Leon to clarify those risks, leading to this updated ruling.
What happens next is likely another round of appeals, with the possibility the case escalates further as construction continues underground.
For now, the ballroom itself remains on hold.
