Donald Trump has disclosed that a large, previously undisclosed military facility is being constructed beneath a new ballroom at the White House, raising questions about transparency and oversight.
According to Trump, the project includes a “massive complex” being built below the planned $400 million ballroom — a development that was not publicly detailed until now.
The underground facility is reportedly being developed by the U.S. military and includes enhanced security features such as reinforced infrastructure and advanced protective systems.
“Now, the military is building a big complex under the ballroom, which has come out recently because of a stupid lawsuit that was filed.”

“We have all bulletproof glass, we have drone-proof roofs, ceilings.”

The president said the project is intended for national security purposes, although it was originally meant to remain confidential.
The new ballroom is being constructed following the demolition of the White House East Wing, a move directed by Trump last year. The ballroom itself is expected to cost approximately $400 million and represents a significant structural addition to the historic presidential complex.
Trump revealed details of the underground construction while speaking to reporters aboard Air Force One on March 29, 2026.
The revelation has prompted concerns among policymakers and observers about the scope, funding and authorization of the project.
Neither the White House nor the Department of Defense has released additional information about the facility, leaving key questions unanswered regarding its purpose and long-term use.
Congressional oversight committees are expected to examine whether the project complies with federal regulations and whether proper approvals were obtained.
While national security projects often require confidentiality, the disclosure has sparked debate over the balance between secrecy and public accountability — particularly for construction activity at one of the most closely monitored government sites in the country.
Critics argue that large-scale developments on White House grounds should involve greater transparency, while supporters may view the project as a necessary investment in security infrastructure.
The reported construction reflects a broader trend of integrating advanced security features into government facilities amid evolving threats, including drone technology and cyber-physical risks.
However, projects of this scale — especially those involving military infrastructure — typically undergo rigorous review processes. The lack of publicly available details has heightened scrutiny and could lead to increased political and legal challenges.
The situation also underscores ongoing tensions between executive decision-making authority and institutional oversight, particularly when sensitive national security initiatives intersect with public-facing infrastructure projects.
