"He put baby chickens and mice in the blender," she says of her cousin, chosen by President Trump to head HHS.

Caroline Kennedy on Tuesday warned that her cousin Robert F. Kennedy Jr. is a “predator” ahead of his high-profile confirmation hearings this week to be President Donald Trump’s Department of Health and Human Services secretary,

Kennedy is the country's most well-known anti-vaccine activist, and could soon lead be Trump's top health official.

On abortion, Kennedy wrote last May that he trusted women to make their own decisions and that the procedure should be unrestricted until the baby could be viable outside the womb.

Robert F. Kennedy's aspirations now rest with the Republican-controlled Senate, where he can lose only three GOP votes if all Democrats oppose him.

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).

Senators from both sides of the aisle are expected to carefully examine the nominee's commitment to evidence-based science and his readiness to lead HHS.
