U.S. CDC director Susan Monarez is fired and other agency leaders resign

The White House says CDC Director Susan Monarez was dismissed due to being ‘not aligned’ with U.S. President Trump’s agenda.

NEW YORK -- The director of the United States’ top public health agency has been fired after less than one month in the job, and several top agency leaders have resigned.

Susan Monarez isn’t “aligned with” U.S. President Donald Trump’s agenda and refused to resign, so the White House terminated her, spokesman Kush Desai said Wednesday night.

Her lawyers said she was targeted for standing up for science.

The U.S. Department of Health and Human Services had announced her departure in a brief social media post late Wednesday afternoon. Her lawyers responded with a statement saying Monarez had neither resigned nor been told she was fired.

“When CDC Director Susan Monarez refused to rubber-stamp unscientific, reckless directives and fire dedicated health experts, she chose protecting the public over serving a political agenda. For that, she has been targeted,” attorneys Mark Zaid and Abbe David Lowell wrote in a statement.

“This is not about one official. It is about the systematic dismantling of public health institutions, the silencing of experts, and the dangerous politicization of science. The attack on Dr. Monarez is a warning to every American: our evidence-based systems are being undermined from within,” they said.

Her departure coincided with the resignations this week of at least four top CDC officials. The list includes Dr. Debra Houry, the agency’s deputy director; Dr. Daniel Jernigan, head of the agency’s National Center for Emerging and Zoonotic Infectious Diseases; Dr. Demetre Daskalakis, head of its National Center for Immunization and Respiratory Diseases; and Dr. Jennifer Layden, director of the Office of Public Health Data, Surveillance, and Technology.

In an email seen by an AP reporter, Houry lamented the crippling effects on the agency from planned budget cuts, reorganization and firings.

“I am committed to protecting the public’s health, but the ongoing changes prevent me from continuing in my job as a leader of the agency,” she wrote.

She also noted the rise of misinformation about vaccines during the current Trump administration, and alluded to new limits on CDC communications.

“For the good of the nation and the world, the science at CDC should never be censored or subject to political pauses or interpretations,” she wrote.

Daskalakis worked closely with the Advisory Committee on Immunization Practices. Kennedy remade the committee by firing everyone and replacing them with a group that included several vaccine skeptics -- one of whom was put in charge of a COVID-19 vaccines workgroup.

In his resignation letter, Daskalakis lamented that the changes put “people of dubious intent and more dubious scientific rigor in charge of recommending vaccine policy.” He described Monarez as “hamstrung and sidelined by an authoritarian leader.” He added: “Their desire to please a political base will result in death and disability of vulnerable children and adults.”

He also wrote: “I am unable to serve in an environment that treats CDC as a tool to generate policies and materials that do not reflect scientific reality.”

HHS officials did not immediately respond to questions about the resignations, or to the statement from Monarez’s lawyers.

Some public health experts decried the loss of so many of CDC’s scientific leaders.

“The CDC is being decapitated. This is an absolute disaster for public health,” said Public Citizen’s Dr. Robert Steinbrook.

Michael Osterholm, a University of Minnesota infectious disease researcher, said the CDC departures were “a serious loss for America.”

“The loss of experienced, world-class infectious disease experts at CDC is directly related to the failed leadership of extremists currently in charge of the Department of Health and Human Services,” he said. “They make our country less safe and less prepared for public health emergencies.”

Monarez, 50, was the agency’s 21st director and the first to pass through Senate confirmation following a 2023 law. She was named acting director in January and then tapped as the nominee in March after Trump abruptly withdrew his first choice, David Weldon.

She was sworn in on July 31 -- less than a month ago, making her the shortest-serving CDC director in the history of the 79-year-old agency.

Her short time at CDC was tumultuous. On Aug. 8, at the end of her first full week on the job, a Georgia man opened fire from a spot at a pharmacy across the street from CDC’s main entrance. The 30-year-old man blamed the COVID-19 vaccine for making him depressed and suicidal. He killed a police officer and fired more than 180 shots into CDC buildings before killing himself.

No one at CDC was injured, but it shell-shocked a staff that already had low morale from other recent changes.

The Atlanta-based federal agency was initially founded to prevent the spread of malaria in the U.S. Its mission was later expanded, and it gradually became a global leader on infectious and chronic diseases and a go-to source of health information.

This year it’s been hit by widespread staff cuts, resignations of key officials and heated controversy over long-standing CDC vaccine policies upended by Health Secretary Robert F. Kennedy Jr.

During her Senate confirmation process, Monarez told senators that she values vaccines, public health interventions and rigorous scientific evidence. But she largely dodged questions about whether those positions put her at odds with Kennedy, a longtime vaccine skeptic who has criticized and sought to dismantle some of the agency’s previous protocols and decisions.

Sen. Patty Murray, a Washington Democrat, praised Monarez for standing up to Kennedy and called for him to be fired.

“We cannot let RFK Jr. burn what’s left of the CDC and our other critical health agencies to the ground,” she said in a statement Wednesday night.

The Washington Post first reported Monarez was ousted.
