Health Secretary Robert Kennedy’s Senate testimony Thursday made one thing crystal clear: He won’t be restoring sanity to our public-health bureaucracies, desperate as the need is.

In a Finance Committee grilling focused on his vaccine policy at the Department of Health and Human Services, Kennedy came off as a paranoid kook connecting red strings on a whiteboard.

When Sen. Bernie Sanders (no fan of the pharmaceutical industry himself) pressed him on his criticism of major medical organizations that disagree with him on vaccines, Kennedy raved that they were bought and paid for by Big Pharma.

The American Academy of Pediatrics? It’s “compromised” because its “biggest contributors are the four largest vaccine makers.”

Oh, and the American Heart Association, too, “has been corrupted by the pharma industry.”

Whatever either outfit’s failings (and each has some), this is pathetically simplistic one-villain-for-all-ills conspiracy-theorizing.

Get this: The Centers for Disease Control can’t be trusted either — because chronic illnesses are on the rise: “When my uncle was president, we spent zero on chronic disease. We [have now] spent $1.3 trillion.”

No: Chronic illness is on the rise because 1) fewer other things are killing us, and 2) Americans’ lifestyles keep getting more unhealthy, with less physical activity, far more overeating and (arguably) worsening diets — not because the CDC “didn’t do [its] job,” as RFK Jr. put it.

Look: The CDC and other agencies direly need to re-emphasize science-backed thinking, to rebuild their resistance to the scandalous politicization that marked their Biden-era work.

But Kennedy isn’t advocating sensible reform; he wants to burn down the public-health apparatus and rebuild it in his image to push his anti-science beliefs.

It’s not just his long record of anti-vax idiocy; Kennedy has proudly displayed his kook obsessions on a host of health-related topics, from cellphones cause cancer to processed foods cause mental-health problems.

Kennedy’s tinfoil hat is blocking out all sense, to the point where he can’t even acknowledge basic facts that don’t align with his priors.

Notably, he refused to give a straight answer when Sen. Mark Warner (D-Va.) asked if he believes the COVID “vaccine did anything to prevent additional deaths”: Kennedy dodged, “I would like to see the data and talk about the data.”

He obviously doubts the vaccines saved lives, but knows he daren’t say so.

That is, he won’t grant the indisputable truth that the jab did reduce the risk of serious cases among the most vulnerable, like the elderly and immunocompromised.

So he can’t make important points about how the feds under Biden went horribly overboard, pushing the vax (and endless boosters) on populations that didn’t need them.

Former CDC Director Susan Monarez claims she got axed last week because she wouldn’t preapprove recommendations from RFK Jr.’s newly refilled vaccine advisory committee, which Kennedy denies.

We may never know whose side of the story is true, yet Kennedy clearly is on the warpath to purge the public-health apparatus of any person, policy or idea at odds with his warped worldview.

America needs agencies like HHS and CDC moving toward a sane center, where decisions are based on data-informed evidence.

The more Kennedy opens his mouth, the more obvious it becomes that letting him call the shots is just trading one extreme for another.
