Billionaire Republican front-runner Donald Trump would be the first to tell you that he is the richest and most generous candidate to ever run for president. From the very beginning of his campaign last summer, he has been touting the $102 million he says he has donated to charity over the last half decade.

“I give to hundreds of charities and people in need of help,” Trump told the Associated Press in August. “It is one of the things I most like doing and one of the great reasons to have made a lot of money.”

Perhaps Trump likes donating to charity so much because he has figured out a way to do so while still hanging on to all that money he’s made. A Washington Post investigation into the Donald’s charitable donations over a five-year period—93 pages’ worth of 4,844 contributions—found that not a single one of those contributions came from his own money.

Many of the donations came from the Donald J. Trump Foundation, a charity that carries his name but did not receive a single personal check from him from 2009 through 2014, the Post reported. Instead, it has been largely funded by outside donors, including World Wrestling Entertainment impresarios Vince and Linda McMahon. Trump does, however, decide how these people’s money gets allocated. This includes the quite public $100,000 donation Trump made to the National September 11 Memorial and Museum last week in New York, in the days leading up to the state’s primary, and the fundraising event he held to benefit veterans in Iowa just before its caucuses. In both examples, checks were cut by the foundation, not from Trump’s personal account.

Many of the foundation’s donations centered around Trump’s business endeavors. It made contributions to the American Cancer Society, the Leukemia and Lymphoma Society, and the Dana-Farber Cancer Institute—which all held events at his Mar-a-Lago resort in Palm Beach. The foundation’s second-largest donation on the list went to the charity of a man who settled a suit with one of the billionaire's golf courses after he was denied a hole-in-one prize. It also listed a donation valued at $1,136.56 to “Serena Williams Group” last year, though a spokeswoman for Williams told the Post the money went toward giving the tennis champion a free ride on Trump’s plane to a ribbon-cutting ceremony at a Virginia golf course and a free framed photo of herself.

Beyond simple monetary donations, the investigation found that free rounds of golf and other assorted giveaways for auctions and raffles accounted for much of his charitable giving. Of the 4,844 donations Trump claims he made, the Post found that 2,900 of those were gratis rounds of golf, 175 hotel stays, 165 meals, and 11 spa gift certificates.

Allen Weisselberg, the C.F.O. of the Trump Organization and treasurer of the foundation, told the Post that none of the gifts had come from Trump himself, but called the list incomplete. He said that Trump had freely given away his own money, but would not say how much or provide documentation as proof. “We want to keep them quiet. He doesn’t want other charities to see it. Then it becomes like a feeding frenzy.”
