Meet all 37 White House ballroom donors funding the $400 million build

The projected cost of the 90,000-square-foot build has doubled to $400 million, up from its July estimate of $200 million. President Donald Trump has insisted it will not come out of taxpayers’ wallets, though public funds are being used for underground security work connected to the project, according to the Associated Press.

The ballroom project has taken on new urgency for Trump and his allies after after a suspect allegedly attempted to storm the White House correspondents’ dinner on Saturday, which they have pointed to as evidence that presidents need a secure venue for large events on White House grounds.

“What happened last night is exactly the reason that our great Military, Secret Service, Law Enforcement and, for different reasons, every President for the last 150 years, have been DEMANDING that a large, safe, and secure Ballroom be built ON THE GROUNDS OF THE WHITE HOUSE,” Trump wrote on Truth Social on Sunday. “This event would never have happened with the Militarily Top Secret Ballroom currently under construction at the White House. It cannot be built fast enough!”

The Justice Department also cited the incident as it pressed the National Trust for Historic Preservation to drop its lawsuit challenging the project. In a Sunday letter posted by acting Attorney General Todd Blanche, Assistant Attorney General Brett Shumate wrote that “when the White House ballroom is complete, President Trump and his successors will no longer need to venture beyond the safety of the White House perimeter to attend large gatherings at the Washington Hilton.” The department later filed a court motion asking a judge to reconsider a lower-court pause on construction.

A list released by White House officials and reviewed by Fortune shows all 37 donors helping fund the ballroom—and it includes some of the nation’s largest tech companies, companies with government contracts and members of the administration. 

Their private, tax-deductible donations will be made to the nonprofit Trust for the National Mall. The White House did not release the size of the donations for all 37 listed. Trump has previously said he will pay for some of the project, though his name doesn’t appear on the list.
