The White House has disclosed that the controversial new $1 billion 'Military Top Secret Ballroom' planned for the presidential complex will include a secret underground hospital for Donald Trump, 79, according to a late-night court filing submitted in Washington on Thursday.

For context, the vast ballroom scheme has been bogged down in legal and political wrangling for months. The National Trust for Historic Preservation sued in December after the East Wing was demolished to clear space for a 90,000-square-foot structure without first securing the necessary approvals. A federal judge ordered a halt to above-ground construction, but that ruling has been temporarily stayed while an appeals court panel weighs the case, with oral arguments now pencilled in for 5 June.

The latest twist emerged in a filing by Acting Attorney General Todd Blanche, Trump's former personal lawyer, who is now fronting the White House's increasingly combative defence of the project. Blanche described the proposed $400 million ballroom as a 'gift to the People of the United States,' and blamed the delay on preservationists, he said, were gripped by 'Trump Derangement Syndrome.'

The National Trust has rejected that characterisation. It took the administration to court after the partial demolition of the East Wing, arguing that the White House had sidestepped long-standing protections for the historic site.

The White House's description of the project as including a hospital and medical facilities comes from court filings and administration statements, and the full scope of the underground complex has not been independently disclosed in detail.

Security Fears, An Attempted Assassination, And Donald Trump

The news came after a shocking attack at the White House Correspondents' Dinner in April, when suspected gunman Cole Tomas Allen allegedly opened fire on Secret Service agents at the annual media gala, which is traditionally held away from the White House. In the political aftermath, Blanche publicly urged the National Trust to drop its lawsuit, arguing the country could ill afford delays to major security works. The Trust refused.

Blanche's filing makes clear that Donald Trump has not let go of that rebuff. He accused the D.C.-based nonprofit of failing to show 'appropriate' concern over what he called a planned massacre, quoting its reference to the shooting as the 'recent incident at the White House Correspondents' Dinner' as evidence of a dismissive attitude. 'Enough is enough,' Blanche wrote, in language that reads more like a Truth Social broadside than a standard government brief.

The administration is now leaning hard on the argument that the ballroom is not primarily a party space at all, but a security imperative. Blanche says the complex will include an underground bunker and other fortified structures, and that, once built, major events would be moved there so presidents and guests are less exposed. In his telling, presidents 'not just President Trump, but all future Presidents' should not be forced to 'risk the safety of themselves, their families, and their Cabinet' because of opposition from preservationists.

Then comes the detail that has electrified Washington: buried in the filing is the assertion that the so-called 'Military Top Secret Ballroom' will double as a medical hub for the ageing commander-in-chief.

'The Project, which includes a state-of-the-art hospital and medical facilities, Top Secret military installations, bomb shelters, structures, and equipment, protective partitioning, and other features — is fully designed to protect the President,' Blanche wrote.

No supporting schematics or independent medical assessments were filed alongside that claim. The White House has not provided a public briefing on what 'state-of-the-art' care looks like in this context, or why it could not be delivered through existing facilities. Without those details, the hospital element sits somewhere between bold security planning and a remarkably expensive private clinic inside one of the most politically sensitive buildings on earth.

From Entertainment Venue To Taxpayer-Funded Fortress For Donald Trump

When Donald Trump first unveiled the ballroom plan last July, it sounded almost modest by his standards. He pitched it as a privately funded entertainment venue, a grand space to host visiting dignitaries, donors, and glittering state occasions that would, according to him, cost taxpayers nothing.

That story has not survived contact with Congress. After a federal judge signalled that any non-security-related construction would need explicit congressional approval, the White House swiftly reframed the ballroom as an urgent security project. The national security label unlocked a very different conversation on Capitol Hill, where Trump allies in the Senate are now chasing an eye-watering $1 billion in federal funding tied to the build, a move the administration has warmly welcomed.

According to the White House, hundreds of millions of dollars within that sum would go on 'bulletproof glass, drone detection technologies, chemical and other threat filtration and detection systems.' A further $175 million is earmarked for 'improving security for Secret Service protectees.' The administration has not offered a precise line-item cost for the underground hospital or the other medical facilities referenced in Blanche's filing.

Critics who challenged Trump's initial promise that the project would be entirely covered by private donors are unlikely to feel reassured. That pledge has essentially disintegrated, replaced by a complex security package knitted into the federal budget. Asked earlier this week about the ballooning price tag, Trump reportedly dismissed a female reporter who pressed him on the numbers as a 'dumb person.'

The president has nonetheless pressed ahead with his sales pitch. Showing off glossy renderings of the 'Military Top Secret Ballroom' aboard Air Force One, Trump has predicted the project will be finished in September 2028 and insists it 'will be the finest facility of its kind anywhere in the U.S.A.'

Whether he secures his personalised underground hospital along the way now rests with the courts, congressional appropriators, and a preservation group that has so far proved stubbornly unmoved by both his salesmanship and his anger.
