Ten thousand people have signed a petition circulated by California Congressmember Karen Bass calling on mental health professionals to determine whether Donald Trump is fit to be president. Bass says Trump exhibits all the symptoms of narcissistic personality disorder. The petition reads: “It is entirely possible that some individuals with NPD can successfully function in many careers, but not the Presidency of the United States. We deserve to have the greatest understanding of Mr. Trump’s mental health status before we head to the polls.”
