The man who hopes to be President Donald Trump’s health secretary says he needs to see data showing vaccines are safe, but he dismissed the evidence shown by an influential Republican senator.

Kennedy Jr. is revising his ethics agreement to divest his interest in litigation against an HPV vaccine maker and directing the stake to his adult son, The New York Times reported Friday, citing a written response to questions from senators who are weighing his confirmation as Health and Human Services secretary.

Robert F. Kennedy Jr. was confronted with a number of his baseless claims and a vexing abortion issue. But Republican senators treaded lightly.

Robert F. Kennedy Jr., a former presidential candidate and environmental activist, endorsed Donald Trump last year and threw his weight behind a campaign to “Make America Healthy Again.” For the past two decades he has been best known for airing skeptical views on vaccines.

If confirmed by the Senate, Kennedy would head the Department of Health and Human Services (HHS), which oversees many of the country’s health agencies, from the Food and Drug Administration (FDA) to the Centers for Disease Control and Prevention (CDC).

The questioning comes after Robert F. Kennedy Jr. faced grueling testimony on Thursday to secure the Secretary of Health and Human Services position

Kennedy, a Democrat who ran as an independent but ended up supporting Trump in the 2024 presidential campaign, was grilled by senators over his views on vaccines, abortion, Medicaid and more during two days of confirmation hearings.
