President Donald Trump openly discussed on Sunday the military’s endeavor to construct a substantial facility beneath the ballroom of the White House, a location he holds in high regard.

While aboard Air Force One, Trump provided an update on the ballroom project, showcasing large cardboard illustrations of the latest architectural designs to the press.

“The military is currently developing a significant complex beneath the ballroom,” Trump remarked, referencing a recent lawsuit he described as “stupid” that brought the project to public attention.

The National Trust for Historic Preservation has launched a lawsuit to halt Trump’s ballroom expansion, claiming that the President bypassed the necessary Congressional approval before initiating the demolition of the White House’s East Wing last autumn.

Trump elaborated, “The ballroom will effectively serve as a protective cover for the construction, shielding it from threats such as drones and other potential dangers.”

Government attorneys have argued in court that stopping the construction could jeopardize national security, justifying the continuation of the ballroom project.

The new complex will replace the Presidential Emergency Operations Center, more commonly referred to as the White House bunker, which dated back to the World War II era. 

Democratic President Franklin Roosevelt replaced the original East Wing, constructed during President Teddy Roosevelt’s era, with the two-story version to hide the original White House bunker. 

President Donald Trump gave new details about the military building a ‘big complex’ under his White House ballroom when talking to reporters on board Air Force One Sunday night

The lawsuit has allowed more details about the ballroom project to be released to the public than what the White House has shared. 

When White House press secretary Karoline Leavitt was asked Monday about Trump’s ‘massive military complex,’ she declined to share any additional details. 

‘I cannot tell you more about that, actually, as a matter of fact,’ she said, laughing. 

‘However, the military is making some upgrades to their facilities here at the White House and I’m not privy to provide any more details on that,’ Leavitt added.

Trump said on board Air Force One that not only would the new facility be drone-proof, but the ballroom would have those capabilities too. 

‘We have all bulletproof glass. We have drone-proof roof, roofs, ceiling, everything’s drone-proof and bulletproof,’ Trump said. ‘And unfortunately, we’re living in an age where that’s a good thing.’

The President survived an assassination attempt in July 2024, while campaigning in Butler, Pennsylvania. 

The ballroom project will be voted on this Thursday by the National Capital Planning Commission, one of two panels that traditionally must sign off on these types of projects.

The other group, the Commission of Fine Arts – now filled with Trump allies, including the President’s 26-year-old executive assistant – fast-tracked a ballroom approval vote without seeing a final design in February. 

The NCPC, which is being led by Trump’s White House Staff Secretary Will Scharf, is also filled with the President’s appointees. 

The group heard from dozens of experts and average Americans during a March meeting, that was held online, with only one individual in the hours of testimony saying positive things about the project. 

Others remarked on the size – three times that of the White House residence – and the ‘ugly’ design. 

Trump showed off new design features on Air Force One, including a differently configured staircase on the south end of the ballroom. 

The project will likely sail through the NCPC when the vote occurs Thursday, leaving the lawsuit the only hurdle standing in the President’s way. 

The judge handling the lawsuit, US District Judge Richard Leon, a President George W. Bush appointee, has signaled that the ruling could come as early as this week, the Washington Post reported. 

Leon has also said that he expects his decision to be appealed to the Supreme Court, where Trump-appointed justices help make up the 6-3 conservative majority.
