Health Secretary Robert F. Kennedy Jr. has built a following by speaking to Americans worried about corporate influence over vaccines, drugs, processed foods and pesticides.

But last week, the leader of the "Make America Healthy Again" movement backed a different industry: artificial intelligence.

At a MAHA summit with AI and Silicon Valley executives, Kennedy said the technology would free Americans from "medical tyranny."

He said it would let them check their own medical advice.

Some prominent MAHA voices criticized the move.

They said the movement's leaders are getting close to the corporate interests they once questioned.

Medical experts also said Kennedy's vision of AI as a check on the medical establishment is flawed.

Dr. Zeke Emanuel is a cancer specialist and bioethicist at the University of Pennsylvania.

He said Kennedy "obviously doesn't understand how AI works."

He said AI gathers information from medical literature and case studies.

So users are really getting medical expertise.

HHS spokesperson Emily Hilliard said Emanuel was describing "one narrow use" of the technology.

She said Kennedy wants to give Americans more control of their health data.

She said AI will help doctors work faster and spend more time with patients.

OpenAI and Anthropic sponsored the summit, along with more than a dozen other companies that have business before the U.S. government.

Sponsors paid up to $300,000, and many got speaking slots.

Dr. Robert Malone is a vaccine researcher who recently served on a federal vaccine panel under Kennedy.

He called it "classic pay-to-play."

He and others said the summit showed big companies replacing the grassroots activists who built the movement.

Tony Lyons runs the MAHA Center and related groups.

He said the goal was to build the biggest movement possible.

Kennedy's alliance with Silicon Valley fits broader Trump administration efforts.

President Donald Trump has resisted oversight of AI companies.

Dr. Mehmet Oz and other officials have promoted AI as a fix for U.S. health problems.
