A new book delves into the president’s mental health. 'One comment was from Hal Brown, MSW, a colleague of John Gartner, Ph.D., whom we mentioned in the post. John is the founder of Duty to Warn, an organization intent on warning our country that we are in dire trouble due to our president’s mental instability. More than 60,000 mental health professionals have signed John’s petition, which states: “We, the undersigned mental health professionals, believe in our professional judgment that Donald Trump manifests a serious mental illness that renders him psychologically incapable of competently discharging the duties of President of the United States. And we respectfully request he be removed from office, according to article 4 of the 25th amendment to the Constitution, which states that the president will be replaced if he is ‘unable to discharge the powers and duties of his office.’”' "The Dangerous Case of Donald Trump" I realize this is an old article. But I am fairly new here and have not seen this best-selling book mentioned yet.
