Supreme Court temporarily allows White House ballroom construction

The historic preservation trust argued that Congress is responsible for authorizing whether a president can build structures on land protected or managed by the federal government – in this case, the White House grounds. 

"The Trust has an 'obvious interest’ in challenging the construction of a massive new ballroom on White House grounds that could likely alter the aesthetic, cultural, and historical integrity of one of the most historic sites in the country," lawyers wrote in a brief to the high court.

Solicitor General John Sauer argued the ballroom would be necessary due to several national security features that will be included in its construction. He said the construction includes bomb shelters, a drone port and advanced medical facilities. 

Members of Congress have pointed out that taxpayers would be on the hook for necessary security measures to protect the ballroom, including $155 million for Secret Service, $149 million for the White House military office, and $3 million for the executive residency. 

"The Project is on time and under budget, and the ballroom is funded with approximately $400 million in private donations by President Donald J.Trump and 'some of the most prominent and successful corporations and people in America' – zero taxpayer dollars are needed or required," Sauer wrote. 

Sauer said the lawsuit was pointless because there would be "no way" for current construction to be altered or dismantled. Crews set out with construction in October 2025 as the East Wing of the White House was demolished. 

In a filing to the court, Sauer said the project is expected to be complete several months before the end of Trump's term. 

"Modernizing the East Wing to address security requirements, update its infra-structure, and better allow the President to carry out his Article II duties (like receiving foreign dignitaries) falls well within the statutory text," Sauer said.
