Microsoft committed $10 million to President Trump’s White House ballroom project, and Amazon and T-Mobile each chipped in $5 million, according to an internal donor list obtained by the Washington Post and reported by the newspaper Thursday morning.

The commitments are drawing scrutiny because the ballroom donations aren’t subject to campaign finance limits or disclosure requirements. The money goes through a nonprofit, the Trust for the National Mall, into a White House account the president directly controls.

Of the $333 million raised so far, the vast majority came from companies and wealthy people with interests before the federal government, the Post found, raising concerns among experts that companies could be buying influence with the administration, or feeling pressured to give.

The White House publicly named Microsoft, Amazon and T-Mobile among the ballroom’s donors last October but didn’t disclose the amounts. Other donors asked to keep their names out of it entirely, the Post found, including a subsidiary of mortgage lender Rocket, which committed $10 million weeks after a federal agency approved its acquisition of Mr. Cooper.

The Seattle-area companies have a wide range of dealings with the government as suppliers, regulated businesses and targets of federal scrutiny. Microsoft and Amazon are two of the federal government’s largest technology providers, and T-Mobile requires regulatory approval across its business, from wireless spectrum to acquisitions.

Amazon is facing an FTC antitrust trial next year, focused on its treatment of third-party sellers on its online marketplace. The FTC and 22 states also sued Amazon in August, accusing it of rigging ad auctions to overcharge advertisers.

Microsoft is at odds with Vice President JD Vance and the Labor Department over claims that the company laid off American workers while sponsoring foreign workers for permanent residency, leading the department to suspend the company from the program.

Apple and Nvidia were among the top contributors at $25 million each, according to the list of 67 donations above $10,000. Microsoft’s $10 million puts it in the next tier with Palantir and Lockheed Martin, while Amazon and T-Mobile joined Meta, Cisco and ServiceNow at $5 million.

White House spokesman Davis Ingle told the Post that the donors are “a wide array of great American companies and generous individuals, all of whom are contributing to make the People’s House better for generations to come.”

A Microsoft spokesperson said the company didn’t have a comment beyond what has been publicly reported. We’ve contacted Amazon and T-Mobile for comment.
