September 4, 2025 — Washington, D.C.
Robert F. Kennedy Jr., the U.S. Secretary of Health and Human Services, was sharply questioned for nearly three hours Thursday during a Senate Finance Committee hearing. Senators from both parties pressed him on vaccine policy, his leadership at the Centers for Disease Control and Prevention (CDC), and his history of controversial remarks on public health.
A Contentious Start
From the outset, lawmakers made clear the hearing would not be routine oversight. Chairman Ron Wyden (D-Ore.) criticized Kennedy’s skepticism toward vaccines, warning that such rhetoric could jeopardize lives. Senator Elizabeth Warren (D-Mass.) demanded Kennedy’s resignation, calling his leadership “a danger to public health.”
Republican Senator Bill Cassidy of Louisiana, a physician, joined in the criticism. He accused Kennedy of effectively denying Americans access to vaccines, despite Kennedy’s previous praise for Operation Warp Speed. Cassidy pressed him on the contradictions, suggesting Kennedy’s current policies were undermining pandemic preparedness.
The CDC Shake-Up
Much of the hearing centered on turmoil at the CDC. Kennedy recently fired Director Susan Monarez and oversaw the resignation of other senior officials. Defending his actions, Kennedy said the changes were “absolutely necessary” to restore credibility at the agency after years of public mistrust.
Democrats were unconvinced. Senator Raphael Warnock (D-Ga.) accused Kennedy of destabilizing the nation’s foremost public health institution at a critical time.
Vaccine Skepticism in the Spotlight
Kennedy, long known for questioning vaccine safety, continued to air his skepticism while acknowledging that vaccines have saved “quite a few” lives. At one point, he repeated claims about mRNA COVID-19 vaccines and sudden cardiac deaths among young people. Health experts quickly countered that no scientific evidence supports such a link, a point underscored by fact-checkers covering the hearing.
Bipartisan Rebuke, Uncertain Future
While Democrats uniformly condemned Kennedy’s leadership, some Republicans stopped short of calling for his resignation. Still, the bipartisan criticism underscored the unusual and precarious position Kennedy holds as a member of President Trump’s cabinet.
The hearing ended without resolution, but with calls for further investigation into both Kennedy’s policies and the state of the CDC. As senators filed out, the lingering question remained: can Kennedy continue to lead the nation’s health agencies amid mounting distrust from Congress and the scientific community?
