Health and Human Services Secretary Robert F. Kennedy Jr. further added to the Trump administration’s problematic claims about Tylenol and autism on Oct. 9, alleging during a Cabinet meeting that circumcision-related studies provide evidence that the drug causes the condition when given to children. The studies, however, do no such thing. Weeks earlier, as part of a promised announcement on the causes of autism on Sept. 22, President Donald Trump had repeatedly admonished pregnant women not to take Tylenol, also known as acetaminophen. He also recommended that children avoid the medicine, saying, “Don’t give Tylenol to the baby after the baby’s born.”
