Sen. Bill Cassidy (R-La.) on Sunday delivered a blistering critique of President Trump's executive order aimed at overhauling the childhood vaccine schedule, calling the rationale behind it 'crazy, stupid' and arguing that such moves are eroding public confidence in the president.
In an interview with CNN's Jake Tapper, Cassidy, a physician, did not hold back when asked about the order, which includes a directive to split the combined measles, mumps, and rubella (MMR) vaccine into three separate shots. Tapper pressed Cassidy on whether Trump was perpetuating 'crazy, stupid things being said that undermine faith in immunization,' to which Cassidy replied, 'Yeah, that's a crazy, stupid thing.'
Cassidy then detailed the practical consequences of the proposed change, noting that families would face more doctor visits and higher costs. 'Instead of the child getting two shots, they're getting six. Instead of Mom and Dad missing work twice to bring the child to the doctor, they're missing six times. And instead of the insurance company paying for two visits, they're paying for six,' he said. He warned that this would drive up premiums and undercut affordability.
The Louisiana Republican tied the issue directly to Trump's political standing, saying, 'This is why the president's poll numbers are going down. Because people don't perceive that he knows the reality of their life.' He later added, 'This is going backwards. We need to go forwards.'
The order, signed by Trump on Monday, builds on broader efforts by the administration and Health and Human Services Secretary Robert F. Kennedy Jr. to reduce the number of recommended childhood vaccines. It also directs HHS to enhance vaccine safety research, with a particular emphasis on autism—a nod to long-debunked claims linking vaccines to the condition. Trump has repeatedly suggested that rising vaccination rates are behind increases in autism diagnoses, a position that medical experts reject.
Public health officials and pediatricians have widely condemned the idea of separating the MMR vaccine, warning that it would leave children vulnerable to preventable diseases for longer periods. The combined MMR shot has been the standard of care since 1971, when Dr. Maurice Hilleman merged the individual vaccines into a single injection. The varicella (chickenpox) component was added in 2005.
Cassidy's remarks echo similar comments he made earlier Sunday on ABC News's This Week, where he criticized the cost and logistical burdens the split would impose on families. His outspokenness highlights growing Republican unease with the administration's vaccine policies, even as Trump and Kennedy continue to push for sweeping changes.
The controversy comes at a politically sensitive time for the GOP, with the president's approval ratings under pressure and midterm elections looming. Cassidy's pointed critique suggests that vaccine policy could become a liability for Republicans in key races, particularly among suburban parents who prioritize public health.
Meanwhile, the administration's stance has drawn sharp rebukes from medical organizations, which argue that the executive order ignores scientific consensus and could have dangerous public health consequences. As the debate intensifies, Cassidy's willingness to break with the president on this issue signals a potential fracture within the party over how far to go in reshaping federal health policy.
