A Skeptical G.O.P. Senator Makes His Peace With Kennedy

Perhaps no vote was as agonizing for Senator Bill Cassidy, the Louisiana Republican and medical doctor, than his vote to confirm Robert F. Kennedy Jr. as President Trump’s health secretary. Mr. Cassidy wondered aloud for days how Mr. Kennedy, the nation’s most vocal and powerful critic of vaccinations, might handle an infectious disease crisis.

Now, as a measles outbreak rages in West Texas, Mr. Cassidy has found out. It all comes down, he said, to “the gestalt.”

On Monday, days after the Texas outbreak killed an unvaccinated child, Mr. Cassidy, the chairman of the Senate Health Committee, was clipping down a Capitol corridor when he was asked about Mr. Kennedy. He pointed to a Fox News Digital opinion piece in which Mr. Kennedy advised parents to consult their doctors about vaccination, while calling it a “personal” decision.

“That Fox editorial was very much encouraging people to get vaccinated,” he said.

Reminded that Mr. Kennedy had described it as a personal choice, Mr. Cassidy thought for a moment. “If you want to like, parse it down to the line, you can say, ‘Discuss with your doctor,’” Mr. Cassidy said. “He also said, ‘We’re making vaccinations available. We’re doing this for vaccination. We’re doing that for vaccination.’ So if you take the gestalt of it, the gestalt was, ‘Let’s get vaccinated!’”

Mr. Cassidy’s assessment — that the whole of Mr. Kennedy’s message was more than the sum of its parts — reflects how the measles outbreak has put a spotlight on how Mr. Trump’s unorthodox choice to run the country’s top health agency has brought a once-fringe perspective into the political mainstream, creating discomfort for some Republicans.

As the founder and chairman of his nonprofit, Children’s Health Defense, and later as a presidential candidate, Mr. Kennedy has repeatedly downplayed the benefits of vaccination. He has also repeatedly suggested that the measles, mumps and rubella vaccine causes autism, despite extensive research that has found no link.
