It was clear even before he got the job that Robert of Kennedy Jr.'s tenure as Secretary of Health and Human Services would be defined by one question.

Here's how Republican Senator Bill Cassidy laid it out during Kennedy's confirmation hearing.

Does a 70-year-old man, 71-year-old man who spent decades criticizing vaccines and who's financially vested in finding

fault with vaccines, can he change his attitudes and approach now that he'll have the most

important position influencing vaccine policy in the United States? Before he entered politics,

Kennedy made a career out of stoking doubt about vaccines.

He promoted theories contradicted by mountains of scientific evidence, like the idea that vaccines cause autism.

And he suggested that many common vaccines, which have been studied for decades,

and administered to hundreds of millions of people that they haven't been adequately tested, as he argued, on Pierce Morgan uncensored on Talk TV.

Therefore, we do not know what the risk profile for any of these products are, and we do not know for any...

In the Senate, Cassidy ultimately concluded that Kennedy could change his attitudes and approach.

He voted in favor of Kennedy's nomination.

He said Kennedy promised to work within the current vaccine approval system and preserve information on the CDC website,

pointing out that vaccines do not cause autism.

We need a leader at HHS who will guide President Trump's agenda to make America healthy again.

Based on Mr. Kennedy's assurances on vaccines and his platform to positively influence Americans' health,

it is my consideration that he will get this done.

Democrats took a different view. Here's Senator Patty Murray of Washington State.

Republicans are choosing to pretend it like it is in any way believable that RFK Jr. won't use his new power to do exactly the

thing he's been trying to do for decades undermine our vaccines. Well, six months into the Trump

administration, RFK Jr. now has a track record we can dig into.

Consider this.
