WASHINGTON (AP) — Robert F. Kennedy Jr. has said vaccines are not safe. His support for abortion access has made conservatives uncomfortable. And farmers across the Midwest are nervous over his talk of banning corn syrup and pesticides from America’s food supply.

If approved, Kennedy will control a $1.7 trillion agency that oversees food and hospital inspections, hundreds of health clinics, vaccine recommendations and health insurance for roughly half the country.

Kennedy is nominated to lead the Department of Health and Human Services, a position that would give him enormous control over public health in America.
