Timothy Mellon, a reclusive banking heir, transferred a $5.5 million Connecticut estate to Children's Health Defense, the anti-vaccine group founded by Robert F. Kennedy Jr. The 300-acre property includes amenities like a pool and tennis court. Mellon, who donated $150 million to Trump's super PAC and $25 million to RFK Jr.'s in 2024, maintains access to parts of the land while covering maintenance costs.

The estate donation reveals the financial connections between Mellon, RFK Jr., and their shared anti-vaccine advocacy. Children's Health Defense has disseminated vaccine misinformation, including unproven claims linking vaccines to autism. The organization's revenue ranges from $15-23 million annually. RFK Jr. stepped down as chairman in 2024 before becoming HHS secretary.

Mellon transferred the property at no cost in August but retained rights to a family cemetery. The 83-year-old heir has spoken with pride about building the estate. The donation shows how closely tied Mellon has become with Kennedy's work against vaccines despite claiming he met Kennedy in person just once.
