Mellon Gave $4.5M Estate to RFK Jr.’s Anti-Vaccine Nonprofit
Timothy Mellon, the reclusive banking heir who became the largest disclosed donor to both President Donald Trump and Robert F. Kennedy Jr. during the 2024 election, transferred two adjacent Connecticut properties valued at approximately $4.5 million to Children’s Health Defense (CHD), the anti-vaccine nonprofit founded by Kennedy, according to a report by Political Wire published June 2, 2026. The donation, which occurred in 2025 and was first reported by The New York Times, deepens the financial ties between one of America’s most consequential political donors and the anti-vaccine movement.
The Donation
The properties span approximately 300 acres at the confluence of the Connecticut and Eightmile Rivers in Lyme, Connecticut, and include a pool, tennis court, and several buildings. Property records show the transfer was completed in 2025, though it was not publicly reported until now. The New York Times valued the estate at approximately $4.5 million, while other estimates place it closer to $5.5 million.
Children’s Health Defense, which Kennedy founded before launching his independent presidential bid, is one of the most prominent anti-vaccine organizations in the United States. According to the BBC, the group has filed nearly 30 federal and state lawsuits since 2020 challenging vaccine mandates and public health policies.
Mellon’s Extraordinary Political Spending
Mellon, 83, is the grandson of Andrew Mellon, who served as U.S. Treasury Secretary under Presidents Harding, Coolidge, and Hoover. He inherited approximately $100 million from family trusts and built a railroad empire through Guilford Transportation Industries, later selling Pan Am Railways to CSX for $600 million in 2022. Forbes estimates the Mellon family’s total net worth at $14.1 billion.
Mellon’s political giving has been staggering in scale. From January 2020 to June 2024, he gave $227 million to federal candidates and committees, nearly all of it to Republicans. By October 2024, his donations to MAGA Inc., the primary super PAC supporting Trump, had reached $150 million. He also gave $25 million to American Values 2024, a super PAC backing Kennedy’s independent presidential campaign.
In 2025, Mellon donated $130 million to help pay members of the U.S. Armed Forces during the federal government shutdown, a gesture that amounted to approximately $100 per service member, according to The New York Times.
A Shared Anti-Vaccine Agenda
The property transfer to Children’s Health Defense represents a different kind of support than Mellon’s previous political donations. Rather than funding electoral campaigns, this gift directly supports CHD’s ongoing operations and legal battles against vaccine mandates. As Political Wire noted, the donation “shows how tightly intertwined Mr. Mellon has become with Mr. Kennedy and their shared work against vaccines.”
Mellon’s simultaneous support for both Trump and Kennedy during the 2024 election fueled speculation that he viewed Kennedy’s candidacy as a spoiler to hurt President Joe Biden. Democrats accused Mellon of “propping up RFK Jr. to be a spoiler for Trump.”
The Reclusive Donor
Despite his outsized influence on American politics, Mellon remains an intensely private figure. According to Wikipedia, he reportedly communicates by fax, has little interest in meeting candidates, and has been described as “socially awkward” by those who know him. He lives on a ranch in Wyoming and has given only a handful of media interviews in his lifetime.
Mellon’s 2015 self-published autobiography, “panam.captain,” revealed deeply controversial views. In it, he described social safety net programs as “slavery Redux” and wrote that Black people “became even more belligerent” after social programs expanded in the 1960s and 1970s. The book also criticized teacher unions, women’s studies, LGBT studies, and African American studies in higher education.
Family Tension
The Vanity Fair profile of Mellon published in September 2024 revealed significant tension within the Mellon family over his political activities. One family member told the magazine that Mellon’s father, Paul, “would be appalled” at his son’s support for Trump. Another relative described Mellon’s politics as a “libertarian viewpoint that’s become radicalized.”
What’s Next
The donation raises questions about the intersection of big money and anti-vaccine activism. It remains unclear what specific use Children’s Health Defense will make of the Connecticut properties, and whether Mellon received any tax benefits from the charitable donation. The transaction may also attract regulatory scrutiny given the size of the gift and the political connections of the parties involved.
As the 2026 midterm elections approach, Mellon’s continued role as a financial powerhouse in American politics — now extending beyond electoral campaigns into the nonprofit sector — underscores the enduring influence of ultra-wealthy donors in shaping both the political and public health landscape.
