Dozens of employees at the Centers for Disease Control and Prevention (CDC) staged a walkout on Thursday, joining supporters in a protest of changes made to the agency under the leadership of Health and Human Services Secretary Robert F. Kennedy Jr.
Since President Donald Trump returned to the White House and appointed Kennedy, the CDC and other public health agencies have seen staff firings and layoffs, policy changes that experts warn are dangerous, and even violence directed toward public health workers.
Protests, resignations and firings at the CDC
CDC employees walked out and joined supporters outside the organization’s headquarters in Atlanta in a “clap out” protest, in which the crowd clapped in addition to marching and holding signs. A host of changes inflicted on the agency led to this moment. The immediate motivation for the protest was to show support for three top CDC officials who resigned from the agency over objections to changes made by Kennedy concerning vaccine policies and were escorted out of the building on Thursday. The resigning experts say that new vaccine restrictions are being implemented without reviewing data and warn that they could endanger public health.

The resignation of senior leaders at the CDC comes after Trump fired CDC Director Susan Monarez on Wednesday, only weeks after she had been confirmed by the Senate and taken over the agency. Her firing came after clashes with Kennedy; Monarez reportedly refused to carry out Kennedy’s orders to fire several experts from the CDC or to implement vaccine restrictions that Kennedy, a long-time vaccine skeptic, supported. Through her lawyers, Monarez said that she prioritized “protecting the public over serving a political agenda.” Monarez has been replaced for now by Jim O’Neill, who currently serves as a deputy to Kennedy at HHS. The White House, meanwhile, is defending Trump’s firing of Monarez for not being “aligned with the president’s mission to make America healthy again.”

Layoffs and violence at the CDC prompt opposition
This tumultuous week at the CDC comes as the agency and the nation’s public health infrastructure have seen significant turmoil under the leadership of Trump and Kennedy. Within days of taking office in January, Trump froze various operations of the CDC and other public health agencies, such as the Food and Drug Administration and the National Institutes of Health. Earlier this month, hundreds of CDC employees were laid off, including employees who worked in violence prevention, just days after a reported vaccine skeptic targeted the CDC in a shooting that killed an Atlanta-area police officer.
After the shooting, employees at the CDC and many others pointed the finger at the anti-vaccine rhetoric of Kennedy and others as stoking violence against medical experts and public health workers. Hundreds of HHS employees signed a letter to Kennedy, accusing him of being “complicit in dismantling America’s public health infrastructure” and calling him out for “repeatedly spreading inaccurate health information.” The letter urged Kennedy to revise his rhetoric and policies to ensure the safety of HHS employees and the public.
So far, it seems Kennedy has no intention of dialing back his anti-vaccine rhetoric and policies, with the president’s backing. As experts warn of risks to the public and dangers to public health workers, employees at the CDC are likely to continue pushing back against the agenda of Kennedy and Trump.
