Calley Means, an influential adviser to Health Secretary Robert F. Kennedy Jr. and the brother of President Trump’s nominee for surgeon general, quietly departed the White House at the end of his term as a special government employee in September 2025. Means has acted as the health secretary’s right hand, coordinating a major presidential commission report on what it described as the dire state of children’s health and sparring on television and online with vaccine scientists and doctors who objected to Mr. Kennedy’s campaign to remake American medicine. Means co-founded the wellness company Truemed, which helps people buy items like Peloton bikes and $8,000 saunas with money not subject to federal income taxes, making it a potential beneficiary of Trump administration plans to broaden the pool of people eligible for such tax-advantaged spending.
