President Donald Trump has stated he would share the names of private donors funding his White House ballroom project, but only a partial list has been made public nearly a year after the project began. In October, the White House released an initial list of 37 donors, including major corporations such as Comcast, Apple, Amazon, Microsoft, Google, Meta, Lockheed Martin, and Coinbase, as well as individuals and family foundations. However, the White House did not reveal the amount each company donated or whether they made additional contributions after the initial 2025 dinner. Since then, no additional donors have been disclosed by the Trump administration, though a few, like Nvidia and Vantive Healthcare, have acknowledged donations independently. Democrats in Congress and government transparency groups have expressed concerns about potential conflicts of interest and the possibility of federal favoritism toward anonymous donors. Trump initially estimated the ballroom would cost $200 million, fully funded by private donors, including himself, though it is unclear whether he has contributed to the project. The estimated cost has since risen to at least $400 million, according to the administration’s latest figures. Additional taxpayer funds have also been allocated for security improvements across the White House complex, which may include the ballroom site. The donations are directed through the Trust for the National Mall, a tax-exempt nonprofit that has not responded to requests for comment. Donors can typically deduct their contributions from their federal income taxes. A person involved in fundraising for the ballroom told NBC News that they were seeking donations of $2.5 million to $5 million, with the tax deduction being a key incentive for contributors. Congressional Democrats have called for more transparency, arguing that the public has a right to know if companies or individuals are donating to a project Trump has personally prioritized in hopes of gaining benefits from his administration. The House Natural Resources Committee and the Oversight and Investigations Subcommittee have requested more information from the National Park Service and the Trust for the National Mall. Democratic senators, including Richard Blumenthal, have also pressed donors directly for details, with groups like Public Citizen raising concerns about possible conflicts of interest. Public Citizen’s analysis found that over half of the publicly identified corporate donors have received new or larger government contracts since October, totaling over $50 billion. The group also noted that 16 of the 27 donors are currently facing or have had federal enforcement actions suspended by the Trump administration. The Trump administration has argued that the ballroom and surrounding military complex are essential for national security, a claim it presented to several lower courts before appealing to the Supreme Court. In late August, the Supreme Court ruled 5-4 to allow the project to continue. Chief Justice John Roberts joined the three liberal justices in dissent, stating the plans are “likely unlawful.” Trump has insisted that no taxpayer money is being used for the ballroom, but at least $300 million in Secret Service funds have been redirected to the White House for security upgrades, which may also apply to the ballroom. Republicans had previously suggested using $1 billion in taxpayer funds to secure the ballroom project, but that proposal did not move forward. Trump has continued to emphasize the need for security, particularly after a recent incident in which a gunman attempted to enter the White House Correspondents’ Dinner. He has suggested that future events, like the Correspondents’ Dinner, could take place in a more secure ballroom on the White House campus. However, the event is hosted independently by a nonprofit group of journalists. Trump has criticized opponents of the ballroom, calling them “very disloyal to our country.” The Trump administration says the project is about 65% complete, with 250 workers operating 20 hours a day to finish it by the summer of 2028. Trump has described the ballroom as “a gift from great patriots of this country.”
