Donald Trump made a deliberate effort to hype his White House press conference on autism. The announcement was ridiculous, even by Trump standards. But as the dust settles on this fiasco, there was one additional element to the event that lingered for me: Why on earth would anyone take medical advice from this guy? Trump, who has literally no background in science or medicine, presented himself as some kind of authority on the subject matter, dispensing all kinds of misguided and potentially dangerous medical advice about medications and vaccinations. Trump is, in other words, arguably the last person anyone should ever turn to for medical advice, despite his eagerness to dispense it.
