The estimated cost of the 90,000-square-foot build has topped $300 million, up from its July estimate of $200 million. President Donald Trump has insisted it will not come out of taxpayers’ wallets. A list released by White House officials and reviewed by Fortune shows all 37 donors footing the bill instead — and it includes some of the nation’s largest tech companies, firms 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.
