Health Secretary Robert F. Kennedy Jr. was reportedly part of a phone call last week with an activist in Texas helping distribute holistic and unproven remedies to families affected by the measles outbreak.

In Texas specifically, a total of 223 people have contracted measles since the outbreak began in January, with at least 29 people, mostly children, requiring hospitalization. One child, who was unvaccinated, has died from measles, while a second unvaccinated person’s death is currently being investigated by health officials.
