WASHINGTON — The undisputed architect and leader of the Make America Healthy Again movement has arrived for a rare interview.

Health and Human Services Secretary Robert F. Kennedy Jr. an attorney and activist, has spent his first year in office radically transforming the intersection of government and healthcare. Under his leadership, the nation’s vaccine guidelines have been rewritten. He’s literally flipped the food pyramid and withheld billions of dollars in grants.

We are here to question Kennedy about his MAHA movement, as part of our research for Episode Two of Extremely Normal, a show that examines how movements, ideas and leaders once considered fringe have now become integral to mainstream American politics.

Perhaps nobody better embodies this trend than Kennedy. Once ridiculed and dismissed for his nonconformist views on vaccines, nutrition, and exercise, Kennedy now leads a vast legion of followers and acolytes.

About 4 in 10 parents identify as MAHA supporters, according to a poll by the Kaiser Family Foundation/Washington Post.
