From the link:
“In February, the Centners welcomed a special guest to speak to students: Robert F. Kennedy Jr., the prominent antivaccine activist. (Mr. Kennedy was suspended from Instagram a few days later for promoting Covid-19 vaccine misinformation.) This month, the school hosted a Zoom talk with Dr. Lawrence Palevsky, a New York pediatrician frequently cited by anti-vaccination activists.”
This explains it.
So it’s RFK Jr, not Calypso Louie.
