President-elect Donald Trump says he will nominate anti-vaccine activist Robert F. Kennedy Jr. to serve as secretary of the Department of Health and Human Services.

While Kennedy insists he is not anti-vaccine and claims he has never advised the public to avoid vaccination, he has repeatedly expressed opposition to vaccines. On a podcast, he stated, "There's no vaccine that is safe and effective" and has urged people to resist CDC guidelines on childhood vaccination schedules.

Kennedy Jr. was himself a Democrat until he campaigned in this year's presidential campaign as an independent focused on health care. But he abandoned the race after receiving a pledge from the Republican Trump that he'd be given a high-ranking position in health policy should Trump return to power.
