Twenty-five researchers made a drastic break away from ethical standards by meeting at Yale University on Thursday to discuss evidence questioning the commander-in-chief's mental health.
They were unanimous in their conclusions that the president suffers a combination of personality disorders.
The psychiatrists defended the move by saying it was their 'ethical responsibility' to warn the American public about the 'dangers' Trump poses to the country.
Speaking to Daily Mail Online, they insisted the president displays anti-social, narcissistic and chauvinistic tendencies that, they believe, are grounds for impeachment.
However, other mental health experts have hit out at the conference, saying that such a 'diagnosis' is not possible without a one-on-one consultation.
And Connecticut Republican Party Chairman JR Romano accused the group of 'throwing ethical standards out the window because they cannot accept the election results'.
Dr James Gilligan, a psychiatrist and professor at New York University, said many psychiatrists have been timid about approaching the topic because of the Goldwater rule.
The rule states it's unethical for psychiatrists to give a professional opinion about public figures they have not examined in person.
However, Dr Gilligan insists his and his colleagues' duty comes from the Duty to Warn, a concept about when a medical professional fails to warn 'victims' when someone communicates an explicit threat of danger.
'Not any pun intended, but in this case the Duty to Warn trumps the Goldwater rule,' Dr Gilligan told Daily Mail Online.
'And in this case, there's a professional obligation to notify the public and if we remain silent, we're passively going along with it.'
The group, organized by psychiatrist Dr John Gartner, has considered the president - who's fast approaching his 100th day in office on April 29 - an unfit leader for the US.
They claim that President Trump suffers from a combination of anti-social personality disorders and extreme narcissism.
Dr Gilligan said he can point to multiple examples that predict Trump's dangerous tendencies.
They cite the incident with Billy Bush as an example of chauvinistic behavior - when Trump was recorded saying that he could grab women 'by the pussy' and get away with it because of his celebrity stature.
