Washington — The White House on Thursday formally appealed a federal court ruling that halted above-ground construction of a proposed new ballroom complex, arguing the project is integral to national security and cannot be separated from classified underground infrastructure.
The appeal follows a decision by U.S. District Judge Richard J. Leon, who reaffirmed that while limited subterranean work could continue, the administration must cease all above-ground construction unless authorized by Congress.
Officials within the administration of Donald Trump said in newly disclosed filings that the project extends far beyond a ceremonial event space. According to the appeal, the underground portion of the complex is designed to house a fortified continuity-of-government bunker, a fully equipped medical facility capable of operating during national emergencies, and what one official described as an “active defensive missile system,” or nuclear missile silo.
While prior court proceedings acknowledged the existence of a bunker and medical components, the administration’s latest arguments mark the first time it has publicly linked the site to a missile capability, framing the entire structure as a unified defense installation.
“The above-ground structure is not ornamental,” a senior administration official said, speaking on condition of anonymity due to the sensitivity of the project. “It is a protective shell for critical national nuclear defense infrastructure.”
Judge Leon, in his ruling earlier this week, rejected the administration’s broader interpretation of national security exemptions, writing that such claims do not permit “otherwise unlawful construction” and criticizing the government’s position as overly expansive.
The legal dispute centers on whether the executive branch can proceed with major alterations to the White House without congressional approval. The ballroom project—estimated at roughly $400 million and already underway following the demolition of the historic East Wing—has drawn criticism from preservation groups and lawmakers.
The National Trust for Historic Preservation, which brought the lawsuit, maintains that the administration has overstated security justifications to bypass legal requirements. In a statement Thursday, the group said the new disclosures “raise more questions than they answer” about the scope and legality of the project.
Legal analysts say the administration’s appeal, now before the U.S. Court of Appeals for the D.C. Circuit, could hinge on how courts balance executive authority in matters of national security against statutory limits on federal construction.
In the meantime, construction activity at the site remains partially restricted. Lower courts have permitted some underground work tied directly to security needs to continue temporarily, while broader questions about the project’s legality move through the appeals process.
The administration has indicated it is prepared to take the case to the Supreme Court if necessary.
