Congresswoman Dr. Kim Schrier (D-WA) recently flexed her credentials as a pediatrician in a testy exchange with HHS Secretary Robert F. Kennedy, Jr. in a House Energy Committee hearing on Tuesday after Kennedy had dismissed every member of the CDC’s Vaccine Advisory Panel.

It did not go well for Mr. Kennedy. Unlike Dr. Schrier, Mr. Kennedy has never treated measles, bacterial meningitis, or pertussis.
