Trump and RFK Jr. Promote Unproven Tylenol-Autism Link in National Speech

In September 2025, President Trump and Health and Human Services Secretary Robert F. Kennedy Jr. delivered a nationally televised speech and policy announcement linking acetaminophen (Tylenol) use during pregnancy to a rise in autism diagnoses, despite broad scientific consensus dismissing any causative relationship. Trump urged pregnant women to 'avoid Tylenol' and Kennedy echoed these claims in a Cabinet meeting, calling critics 'anti-Trump.' Medical and autism advocacy groups condemned the remarks as irresponsible and unsupported by the evidence, warning that federal health leadership was promoting misinformation that could harm public health.
