An advocacy group founded by former Vice President Mike Pence is escalating its fight against Robert F. Kennedy Jr., this time with an ad that uses President Trump’s past criticisms of Kennedy to argue against his nomination to lead the Department of Health and Human Services (HHS).

“RFK Jr is a Democrat plant, a radical left liberal,” one clip from May showed Trump saying. “He makes the ‘Green New Scammers’ look very conservative by comparison, and he’s anti-military and he’s anti-vet.… I’d even take Biden over Junior.”
