RFK Jr.’s operation had been building toward this moment for months. On August 23, Kennedy suspended his independent presidential bid and endorsed Trump after what he described as “a series of long, intense discussions” that proved the two were ideologically aligned.

Robert F. Kennedy Jr. wants to revisit federal vaccine recommendations, take fluoride out of public water and boost access to raw milk, among other goals.

Shares in several pharmaceutical and biotechnology companies have fallen since President-elect Trump announced Thursday that he had tapped vaccine skeptic Robert F. Kennedy Jr. to lead the Department of Health and Human Services (HHS).

Democratic Colorado Gov. Jared Polis praised President-elect Trump for nominating RFK Jr. to be the next secretary of the Department of Health and Human Services.

This isn’t the first time Polis, who is seen as a possible 2028 Democratic presidential contender, has shown a willingness to butt heads with his party.

President-elect Trump's decision to tap Robert F. Kennedy Jr as his nominee for secretary of Health and Human Services has elicited mixed reactions from Republicans on Capitol Hill. Why it matters: Kennedy — an anti-vaccine activist who previously ran against Trump for president before dropping out and endorsing him — will need to lock down support from key senators to get through the conformation process.
