Senate HELP Committee Chair Bill Cassidy (R-La.) delivered a blunt message to Robert F. Kennedy Jr. during Thursday’s hearing, signaling serious concerns about his nomination for Health and Human Services (HHS) secretary.
“I’ve been struggling with your nomination,” Cassidy stated in his closing remarks, a potential roadblock for Kennedy, given Cassidy’s influential position on the Senate Finance Committee. If Cassidy votes against Kennedy in the panel’s decision, the nomination may not advance.
The Louisiana senator expressed deep skepticism about Kennedy’s stance on vaccines, questioning whether he could be trusted to uphold sound public health policy. Cassidy specifically criticized Kennedy’s history of vaccine skepticism, warning that such views could erode trust in essential immunizations.
“A worthy movement, called MAHA, to improve the health of Americans?” Cassidy asked. “Or will it undermine it, always asking for more evidence and never accepting the evidence that is there?”
He also recounted a recent case of two children dying in a Baton Rouge ICU from vaccine-preventable diseases. “My concern is that if there’s any false note, any undermining of a mama’s trust in vaccines, another person will die from a vaccine-preventable disease,” Cassidy warned.
Beyond his own reservations, Cassidy’s remarks signal broader challenges for Kennedy’s nomination. Senate Minority Leader Mitch McConnell (R-Ky.), a childhood polio survivor, is unlikely to back a nominee with anti-vaccine ties. Sens. Susan Collins (R-Maine) and Lisa Murkowski (R-Alaska) also remain key votes to watch, with both urging Kennedy to support vaccinations.
Cassidy, up for re-election in 2026, has already drawn a Trump-aligned challenger, State Treasurer John Fleming. Though Cassidy emphasized his desire for Trump’s policies to succeed, he warned that anti-vaccine rhetoric could tarnish Trump’s legacy. “I want President Trump’s policies to succeed,” Cassidy said. “But if there’s someone that is not vaccinated because of policies, of attitudes we bring to the department, and there’s another 18-year-old who dies of a vaccine-preventable disease… The greatest tragedy will be her death. I can also tell you an associated tragedy will be that it will cast a shadow over President Trump’s legacy, which I want to be the absolute best legacy.”
Bottom line: With Cassidy’s support in doubt and broader Senate skepticism, Kennedy’s path to confirmation remains steep.
