Robert F. Kennedy Jr. Defends CDC Purge in Contentious Senate Hearing

Health and Human Services Secretary Robert F. Kennedy Jr. faced intense bipartisan scrutiny during a three-hour Senate Finance Committee hearing on September 4, 2025. Lawmakers questioned Kennedy on his "Make America Healthy Again" agenda, specifically his decision to cut US$500 million in mRNA vaccine research funding and restrict COVID-19 vaccine eligibility to seniors and high-risk individuals. Kennedy defended these moves as necessary to shift the U.S. from a "sick care system" to one addressing chronic disease, while critics, including Republican Senator Bill Cassidy, argued the policies effectively deny Americans access to vaccines.

The hearing centered on a leadership crisis at the Centers for Disease Control and Prevention. Kennedy fired CDC Director Susan Monarez less than a month into her tenure and replaced the 17-member Advisory Committee on Immunization Practices with vaccine skeptics. Kennedy characterized Monarez as "untrustworthy," while Monarez alleged in a Wall Street Journal op-ed that she was ousted for refusing to rubber-stamp unscientific recommendations. This turmoil was compounded by the resignation of several senior officials and a letter from over 1,000 HHS employees calling for Kennedy's resignation.

While Democratic senators labeled Kennedy a "charlatan" and a "hazard to the health of the American people," President Donald Trump publicly defended the secretary, stating he likes that Kennedy is "different." In response to the federal restrictions, governors in Massachusetts and California announced plans to manage vaccine insurance and availability independently. Former CDC Director Susan Monarez is scheduled to testify before the Senate health committee on September 17 regarding her termination.
