Yet online, a different narrative of his tenure was playing out as a small but vocal group of Kennedy’s supporters and former employees assailed top Trump administration advisers, claiming they were sabotaging him and redirecting MAHA away from its original goals.

“MAHA is not MAHA anymore,” Gray Delany, a former Department of Health and Human Services official ousted in August, said in a podcast interview that day. “I’m not there, but what I’ve heard of what’s happening today is not the MAHA that we signed up for.”

The criticisms, which grew loud enough that the health secretary took to social media to defend his colleagues two days later, exposed the cracks that are beginning to form within his coalition as it amasses power and broadens in scope.

Several of the environmental advocates and vaccine skeptics who helped propel Kennedy into politics have become impatient with what they view as inadequate action on their priorities. They’re also wary that the Health Department appears willing to collaborate with pharmaceutical companies, tech firms and other big corporations whose motives they don’t trust.

The fissures pose a threat to the cohesion of a movement that has given President Donald Trump an important ally and Republicans access to a new group of voters. They come as cracks have developed in Trump’s own Make America Great Again movement over issues like the Epstein files and the White House’s focus on global diplomacy.

In the wider public, MAHA has enjoyed soaring popularity. About two-thirds of Americans said they supported the “Make America Healthy Again” initiative from the federal government, according to an Ipsos poll from June.

“MAHA’s growth is a sign of its success,” said HHS spokesperson Andrew Nixon. “Secretary Kennedy is leading a broad coalition to make Americans healthier, guided by transparency, accountability and measurable results. The movement’s meaning hasn’t changed and it’s stronger than ever.”

Public health researchers say the genius that fuels Kennedy’s movement — the universal appeal of making Americans healthier — can also cause conflicts by inviting competing interests.

“This is a tale as old as time in politics,” said Matt Motta, a professor at Boston University School of Public Health. “The bigger your tent is, the harder it can be to make everyone happy.”

Frustration rises from within

Kennedy, a longtime environmental lawyer and anti-vaccine activist who helped lead the crusade against COVID-19 shots during the pandemic, has taken many steps to curtail vaccines this year. He pulled $500 million for their development, ousted and replaced every member of a federal vaccine advisory committee and pledged to overhaul a federal program for compensating Americans injured by shots. He also has repeatedly spread false and misleading information about vaccines while in office.

As recently as this week, in a move that thrilled Kennedy’s anti-vaccine base, the Centers for Disease Control and Prevention changed its website to contradict the longtime scientific conclusion that vaccines do not cause autism.

But many of Kennedy’s supporters in what they call the “health freedom” movement say it’s not enough. Some want punishments for companies that profited from vaccine and mask requirements during the pandemic. Others want mRNA-based COVID-19 shots pulled from the shelves, despite scientific consensus that they have saved millions of lives.

In their attacks on the administration last week, a few MAHA influencers and two fired HHS employees suggested White House chief of staff Susie Wiles and Kennedy’s close adviser, Stefanie Spear, were conspiring to limit Kennedy’s ability to restrict vaccines and crack down on pharmaceutical companies.

Some Kennedy supporters latched on to the claims and pointed to Wiles’ career history at a lobbying firm that has worked with Pfizer as evidence she’s trying to undermine him. They also shared years-old social media posts from Spear criticizing Trump.

Kennedy defended his colleagues in two posts on X, saying the MAHA movement has “no better friend in Washington” than Wiles and that Spear has become a Trump loyalist.

“Let’s focus on our extraordinary achievements to date and the monumental work that still needs to be done,” Kennedy wrote. “Let’s build our coalition instead of splintering it.”

The meaning of MAHA now depends on whom you ask

Since the “Make America Healthy Again” slogan debuted on the campaign trail last year, Kennedy and Trump have widened the MAHA tent considerably by inviting anyone into the fold who has concerns about Americans’ health, nutrition and chronic disease.

That’s attracted a diverse crowd, including moneyed interests — among them health data startups, artificial intelligence firms, drug manufacturers and even fast-food companies. Steak ’n Shake recently promoted its fries cooked in beef tallow, saying it was “proud to be part of the MAHA movement.”

At the recent MAHA event in Washington, hosted by the pro-Kennedy group MAHA Action, Kennedy and other federal health officials appeared on a stage that was occupied throughout the day by biotech companies like CRISPR Therapeutics and Regeneron, the brain-computer interface company Neuralink and various AI companies and health startups. The invitation list raised flags for some longtime Kennedy supporters.

“I was not thrilled about some of the people who were there,” said Leslie Manookian, president and founder of the Health Freedom Defense Fund, a nonprofit that promotes bodily autonomy. “I don’t think that we make America healthy again through pills, creams, injections, pharmaceuticals, chips, monitors, devices.”

Tony Lyons, president of MAHA Action, told The Associated Press that the MAHA movement’s strength “comes from its openness to ideas, from its dedication to including all voices, all perspectives, more dialogue, more fierce debate.”

“We don’t want to exclude anyone,” he said. “We don’t want to censor anyone.”

Ethan Augreen, who led Colorado’s volunteer effort for Kennedy’s presidential campaign last year, said he was concerned both by speakers at the event and by a recent Kennedy social media post about meeting with tech leaders to talk about personal health data.

He said he hoped Kennedy would fight corruption in America’s health care system and remove mRNA COVID-19 vaccines from the market.

“There’s definitely some alarm bells going,” Augreen said. “Grassroots MAHA people definitely don’t trust these corporations, and it’s not really apparent whether the administration is just getting in bed with them or really holding their feet to the fire.”

Kennedy and his team thread a needle on the MAHA message

At a recent Oval Office meeting, Kennedy stood with Trump and other administration leaders as they touted a deal with drugmakers Eli Lilly and Novo Nordisk to expand coverage and reduce the prices of weight-loss drugs.

Kennedy had previously expressed skepticism about GLP-1 weight-loss medications and has said he wants to focus on the root causes of disease instead of medicating the public. But he praised the deal, even as he was careful to add it wasn’t a “silver bullet.”

Dr. Mehmet Oz, the administrator of the Centers for Medicare and Medicaid Services, said during the MAHA event that scrutiny of it from Kennedy’s base was “understandable.” He defended the administration as using Trump’s negotiation playbook instead of going “head-to-head with adversaries.”

Several of Kennedy’s core supporters said they see the government as a deeply entrenched bureaucracy that won’t be easy to reform, even as they hope he’ll be able to remove toxins from food and the environment and further restrict vaccines. Kennedy, at an appearance with western governors Thursday, said he doesn’t intend to take away people’s access to vaccines.

Jeffrey Tucker, founder of the nonprofit Brownstone Institute who has rallied support behind Kennedy, said MAHA activists are idealistic but at times naive about the difficulty of government reform.

“It’s very important to hold on to your ideals,” he said. “But if you’re doing nothing but throwing rocks, then you can become a problem.”

Motta, the professor, said regardless of where MAHA goes next, it’s already bigger than any singular policy position.

“Identities do not go away easily,” he said. “They are deeply held; they are deeply integrated into our sense of self. And I would be shocked if this was a movement that faded.”
