Key moments from RFK Jr.'s fiery Senate hearing

Health and Human Services Secretary Robert F. Kennedy Jr. faced a grilling before the Senate Finance Committee on Thursday amid turmoil at the Centers for Disease Control and Prevention (CDC) and his controversial views on vaccines. Kennedy clashed repeatedly with Democrat and Republican senators alike, many of whom questioned Kennedy's handling of vaccine policy. He spent about three hours defending himself and his actions a week after the ousting of Susan Monarez as CDC director and major vaccine changes, including limiting access to the COVID-19 vaccine.
