Trump tying Tylenol to autism 'not based in fact': autism expert

U.S. President Donald Trump on Monday (September 22) linked autism to childhood vaccines and also to the use of popular pain medication Tylenol for pregnant women and children, claims which are not backed by decades of science. Dr. Audrey Brumback, an autism expert and researcher at the University of Texas at Austin told Reuters on Monday that things Trump said at the press conference aren't based in fact.
