A Yale School of Medicine psychiatrist who previously briefed members of Congress on President Donald Trump’s mental state has received thousands of death threats by email, phone and social media, she claims.

Dr. Bandy X. Lee, an assistant clinical professor of psychiatry, told the New Haven Register that the threats, which came primarily via Twitter, have “calmed down a bit” of late after peaking at about roughly 1,000 per day following her private meetings with Congress members, including one Republican senator, in December.

“I was concerned because I was getting a thousand threatening messages a day at one point,” Lee told the newspaper.

Politico reported in January that Lee was summoned to Capitol Hill on Dec. 5 and 6 by lawmakers who were concerned about his behavior at the time. In an interview, she recalled pointing to Trump’s fascination with conspiracy theories and violent videos, as well as denying things he had previously admitted, as problematic signs during the meeting with attentive Congress members.

“One senator said that it was the meeting he most looked forward to in 11 years,” Lee said. “Their level of concern about the president’s dangerousness was surprisingly high.”

Lee, the editor of “The Dangerous Case of Donald Trump: 27 Psychiatrists and Mental Health Experts Assess a President,” which was released in October, claims Trump’s behavior has already led to increased gun violence in the United States and the risk of world war erupting at any moment thanks to his frequent references to the country’s nuclear arsenal.

“My concern is not Mr. Trump’s personal mental health,” she told the New Haven Register. “It is the threat that he poses to the public by virtue of occupying the office of the presidency, and I am acting on my obligation to the public, as professional have an obligation to the public and not just to their private patients.”

Lee made clear that she’s not speaking on behalf of Yale University, which also distanced itself from her statements, saying in a statement to the newspaper that “Dr. Lee’s position and opinions are her own” and do not reflect the views of the 12,000-student university.

Lee also claims she’s not violating the American Psychiatric Association’s “Goldwater Rule,” a 1973 principle than bans psychiatrists from offering opinions on people they have not personally evaluated. APA officials reiterated its commitment to the ethical principle in a statement released earlier this month, saying a “proper psychiatric evaluation requires more than a review of television appearances.” Without mentioning Lee by name, the association also denounced “armchair psychiatry,” calling for an end of physicians providing opinions on public figures during cable news appearances or in books.

But Lee claims she’s not offering an opinion on Trump’s mental health. Instead, she wants him to submit to a full psychiatric examination.

“There is an unprecedented spike in hate crime being reported, schoolyard bullying done in Trump’s name,” Lee told the newspaper.

Lee also cited a 12 percent rise in gun violence during the first 200 days of 2017, based on figures from the nonprofit Gun Violence Archive. But Trump’s greatest threat to peace, she said, is his access to the country’s nuclear weapons.

“With the mental instability that he has shown, psychologically and cognitively, it is very dangerous for that to be in his possession,” Lee told the New Haven Register. “ … What we see from afar includes impulsivity, recklessness, paranoid reactions, a loose grip on reality, rage reactions, a lack of empathy and a constant need to demonstrate power.”

Lee said Trump’s recent perfect score on the Montreal Cognitive Assessment was “meaningless” and called for a cognitive evaluation, saying an MRI or PET scan would have been more useful.

“We need to assess him psychologically, cognitively, neurologically and capacity-wise,” she said. “ … My concerns are not Mr. Trump’s personal mental health. My concern is his situation being in the presidency and the public health effects he is posing.”

A request for comment from the White House press office was not returned, the New Haven Register reports.
