McCullough, like Earhardt, is a familiar face for the Fox audience — and thus a key validator for The Wellness Company’s product. An internist and cardiologist, he became a frequent presence on Fox during the rollout of the COVID-19 vaccines, making at least 37 appearances on its weekday programs in 2021 and 2022.
McCullough used the network’s platform to undermine the public vaccination effort, tout the purported effectiveness of hydroxychloroquine and ivermectin in treating the virus, and claim that an NFL player who was struck in the chest, collapsed on the field, and was diagnosed with cardiac arrest had suffered “vaccine-induced myocarditis.”
McCullough’s COVID-19 vaccine commentary made him an outcast in the medical community.
His former employer, Baylor Scott & White Health, filed a lawsuit against him in 2021, citing “irreparable reputational and business harm” caused by McCullough being identified with his former Baylor titles in interviews (the parties apparently reached a settlement in 2023).
Then in 2022, the credentialing committee of the American Board of Internal Medicine recommended stripping McCullough of his certifications over his vaccine claims. The Journal of Medicine reported in January 2025 that ABIM’s look-up tool identified McCullough’s certifications in internal medicine and cardiovascular disease as “Not Certified, Revoked,” which remains their current status.
But as The Daily Beast reported in a 2023 profile of The Wellness Company, McCullough became “a hero in anti-vaxx circles” — and thus an attractive business partner for Foster Coulson and Dave Lopez, the “Trumpworld-linked investors” who founded TWC that year. They were joined by other “disreputable medical professionals,” including TWC “Chief Epidemiologist” Dr. Harvey Risch, another veteran of Fox's crusade against the COVID-19 vaccine campaign.
As the Beast detailed, the group was “hawking a Goop-like lifestyle brand—complete with supplements, podcasts, telehealth, and even a dating service—to conservative audiences with the help of far-right influencers.”
The company has tried to tap into the right-wing fearmongering of the day. When conspiracy theorists warned in 2024 about a plan to kill off “excess population” through the hypothetical pathogen “Disease X,” The Wellness Company ran sponsored content at outlets like Breitbart and The Gateway Pundit pointing to its “Medical Emergency Kit” as a remedy.
Over the past few months, ads for TWC have also run on the right-wing podcast shows of Candace Owens and Jack Posobiec.
But now with a sponsored Fox & Friends segment, TWC is taking that act to a much bigger audience — one they are counting on to trust the testimonials from McCullough and Earhardt.
