Sen. Bill Cassidy (R-LA) accused HHS Secretary Robert F. Kennedy Jr. of lying about a pledge not to change the childhood vaccine schedule [1].
The dispute highlights a growing rift between the Department of Health and Human Services and the lawmakers who confirmed its leadership. Because the childhood vaccine schedule is a cornerstone of U.S. public health, any attempt to alter it could trigger significant political and medical volatility.
Speaking during an interview on ABC News’s “This Week” on June 30, Cassidy said it is "pretty evident that RFK Jr. lied about changing the vaccine schedule" [1]. The senator said Kennedy broke a pledge he made to secure Cassidy’s Senate confirmation vote [1].
According to Cassidy, the pledge was intended to ensure Kennedy would not attempt to tweak the schedule, and would align with a presidential executive order regarding the matter [1]. Cassidy said Kennedy broke his pledge to not attempt to tweak the childhood vaccine schedule [2].
Kennedy denied the accusations. In a response reported on June 30, Kennedy said, "I’ve kept them all" [3].
The conflict centers on the specific terms of the agreement reached during the confirmation process. While Cassidy maintains the evidence of a broken promise is clear, Kennedy said he has remained faithful to all commitments made to the Senate [1, 3].
The tension comes as the HHS continues to navigate the implementation of federal health policies under the current administration. The public disagreement between a sitting cabinet secretary and a key member of the Senate suggests a breakdown in the trust established during the nomination process [1].
“"It’s pretty evident that RFK Jr. lied about changing the vaccine schedule."”
This confrontation underscores the fragile political coalition that confirmed Robert F. Kennedy Jr. as HHS Secretary. By accusing Kennedy of lying, Sen. Cassidy is signaling to other moderates and health professionals that the administration may be deviating from the assurances provided during the confirmation hearings. If the administration does move to alter the vaccine schedule, it could alienate key GOP allies and lead to legal or legislative challenges over public health mandates.
