For ten years, Bandy Lee, a forensic and social psychiatrist, has been investigating the conduct of President Donald Trump. A former researcher and professor of Law and Psychiatry at Yale School of Medicine, affiliated with Harvard’s psychiatry program, she directs the World Mental Health Coalition, which investigates the psychological capacity of politicians. Not without controversy, her book The Dangerous Case of Donald Trump, published in 2017 during his first term, compiled essays from 27 psychiatrists, psychologists, and other experts on the president’s mental health, an issue that is once again coming to the forefront.
