Sen. Bill Cassidy (R-LA)'s response to a new Robert F. Kennedy Jr. scandal resulted in mockery on MSNBC on Sunday.

As Politico recently reported, "the CDC changed its website, walking back assurances that vaccines do not cause autism and upending decades of work by the agency to combat misinformation about vaccines and autism." Cassidy's response to that was, "Life is lived forward."

On MSNBC, host Eugene Daniels mocked the answer by Cassidy, who is a medical doctor.

"Life is lived forward. That is the best that a senator and a doctor could come up with," he said, teasing that he would start using that line. "I'm living my life forward. Nate has a problem with me. I live my life forward, baby. I can't look in the past."

A second host chimed in, "It's just a remarkable answer considering what he said he wanted from RFK Jr. Promises that he would not, you know, refute vaccine efficacy. And RFK did the opposite. And rather than, you know, taking responsibility for that vote, he seems... he isn't even really pushing back hard on RFK anymore either."
