Power Struggle at the CDC
The Biden-appointed Dr. Susan Monarez, a biosecurity expert and former NIH official, was abruptly removed from her post as CDC director on Wednesday. Her dismissal came just weeks after her Senate confirmation and was reportedly driven by disputes with RFK Jr.’s inner circle, including deputy chief Stefanie Spear. Monarez had resisted pressure to back controversial changes to vaccine guidance and opposed attempts to purge key agency scientists.
Watch now: CDC leaders who resigned sound alarm over direction of agency
The Health and Human Services Department claimed she was out of step with the agency’s goals. However, Monarez’s legal team argues her termination was unlawful, since the CDC director is a presidential appointment requiring Senate confirmation. Her removal triggered an exodus of top staff, including three national center directors and the agency’s chief medical officer.
Mass Resignations and Institutional Collapse
In a span of 24 hours, at least four senior CDC officials resigned in what internal memos described as a protest against political interference and scientific distortion. Among them were Dr. Debra Houry, the agency’s Chief Medical Officer, and Dr. Demetre Daskalakis, a leading authority on immunization policy. The resignations coincided with an earlier attack on CDC headquarters in Atlanta, which left a police officer dead and further strained agency morale.
This dual shock—violence and administrative upheaval—has exacerbated fears among public health experts about institutional collapse. The CDC, long revered as a global leader in health strategy, now faces its most serious crisis in decades. Critics say RFK Jr.’s vision for “Making America Healthy Again” is dismantling decades of medical consensus and driving a wedge between federal agencies and the scientific community.
State Defiance and National Fallout
In the wake of these developments, California, Oregon, and Washington have jointly launched a “West Coast Health Alliance” to maintain their own vaccine recommendations, bypassing what they call the “politicized guidance” coming from Washington. Over 1,000 current and former HHS employees have signed an open letter demanding Kennedy’s resignation, citing “irreparable harm” to public health.
Meanwhile, nine former CDC directors, spanning both Republican and Democratic administrations, published a scathing op-ed warning that Kennedy’s actions could result in preventable deaths and long-term damage to public trust. Senator Bernie Sanders echoed that sentiment, calling the situation a “health emergency driven by ideology.”
Despite the growing backlash, Kennedy defended his actions in a Thursday interview with Fox News, saying the CDC was plagued by “deeply embedded malaise” and required aggressive reform. He reiterated his stance that “some people should not be working there anymore,” signaling more shakeups could be ahead.
