The dean of the Harvard T.H. Chan School of Public Health, who consulted with top Trump health officials ahead of Monday’s warning about Tylenol and autism, was paid at least $150,000 to serve as an expert witness on behalf of plaintiffs in lawsuits against the maker of Tylenol. He had previously disclosed that he had served as an expert witness in the case but not how much money he had made. A federal judge dismissed the suits for lack of reliable scientific evidence. President Trump and federal health officials claimed in a news conference on Monday that there was an established link between Tylenol use during pregnancy and autism.
