A federal judge has issued a revised order blocking above-ground construction of President Donald Trump's proposed $400 million White House ballroom, while allowing underground work on national security facilities to continue. U.S. District Judge Richard Leon clarified his earlier ruling after the Trump administration argued that the entire project was necessary for security reasons.
Core Facts
Judge Leon's order, issued on April 16, 2026, specifies that above-ground construction of the 90,000-square-foot ballroom must halt, but underground work—including the construction of a presidential bunker and other security facilities—can proceed. The ruling comes after the administration appealed, claiming the project was critical to national security.
Deeper Context
Legal and Political Background
The National Trust for Historic Preservation sued the Trump administration, arguing that the demolition of the East Wing and construction of the ballroom required congressional approval. The Trump administration has maintained that the ballroom is privately funded, though public funds are covering underground security upgrades.
Judge Leon's Rationale
In his ruling, Leon rejected the administration's argument that the entire project fell under a national security exemption. He wrote, 'National security is not a blank check to proceed with otherwise unlawful activity.' The judge also criticized the Justice Department's interpretation of his original order as 'incredible, if not disingenuous.'
Administration's Response
The Trump administration had argued that halting construction would jeopardize presidential safety and national security, citing threats from drones, ballistic missiles, and biohazards. The administration has seven days to appeal the ruling to the Supreme Court.
Project Details
The ballroom project, approved by the National Capital Planning Commission, was set to begin above-ground construction this spring. The East Wing was demolished last year to make way for the new structure. The project includes enhanced security features designed to protect the president and sensitive underground facilities.
Ongoing Legal Battle
The case has drawn attention to the balance between presidential authority and congressional oversight in White House construction projects. The administration's appeal to the Supreme Court could further delay the project, which has faced criticism from preservationists and some lawmakers.
