Senator Sanders questions Kennedy on anti-vaccine group ties during HHS confirmation hearing.

During his confirmation hearing for Health and Human Services Secretary, Robert F. Kennedy Jr. faced questions from Senator Bernie Sanders about baby onesies sold by the Children's Health Defense, an anti-vaccine group Kennedy founded. The onesies featured slogans like "Unvaxxed Unafraid" and "No Vax No Problem." Despite resigning from the group, Kennedy maintained his support for vaccines and good science. Sanders questioned Kennedy's stance on vaccines and demanded he remove the products, highlighting concerns over vaccine politicization.
