The claim

“Senator Bernie Sanders confronted Robert F. Kennedy Jr. about his rejection of germ theory at a congressional hearing on Wednesday.”

Ars TechnicaNews reportApril 23, 2026

Reporting on a Senate HELP Committee hearing with Health Secretary Robert F. Kennedy Jr.

Our verdict

True

Sanders pressed Kennedy on germ theory at an April 2026 HELP Committee hearing, and Senator Cassidy rebutted Kennedy's cited studies.

What we found

Ars Technica reported that Sanders asked Kennedy whether he still denied core claims of germ theory, which Kennedy questioned in his 2021 book. Kennedy cited studies that Senator Bill Cassidy then read out to show they did not support him. We could only access reposts of the report, not a transcript.
