Two possibilities…

• RFK does have a supplement/snake oil business(?) if I recall correctly, so he does have a personal stake in "MAHA"
• This sounds nuts but there is a possibility that he really believes what he is doing is correct, and became a useful idiot in the process

And don’t forget the people within CDC who are more involved… I will never forgive Jayantha “Jay” Bhattacharya and Matthew Memoli for dismantling the NIH. Btw the motive for Bhattacharya was very clear: he was an economist who proposed a fringe theory on COVID that was widely criticized, but then doubled down and essentially became entrenched in antivax himself. Which is also why I wonder if RFK also got high on his own supply
