'The quackery': MSNBC analyst goes off on Trump ally for questioning polio vaccine

Reacting to a New York Times report that a lawyer representing Robert. K. Kennedy Jr. has asked the FDA to revoke approval of the polio vaccine developed by Jonas Salk in 1955, MSNBC contributor Mike Barnicle angrily called out the potential Donald Trump Cabinet member.

With Kennedy selected by the president-elect to head up the Department of Health and Human Services despite having no expertise in the sciences, Barnicle recalled growing up in a time when polio was a scourge that crippled countless children.
