Since past attacks have failed to have any effect, their latest attempt has been to get some psychiatrists to argue that Trump isn't mentally fit for office, and should be impeached because of that.
One should note that since these are actual professional psychiatrists, what they are doing is against the American Psychiatrist Association code of ethics. Said code states:
"On occasion psychiatrists are asked for an opinion about an individual who is in the light of public attention or who has disclosed information about himself/herself through public media. In such circumstances, a psychiatrist may share with the public his or her expertise about psychiatric issues in general. However, it is unethical for a psychiatrist to offer a professional opinion unless he or she has conducted an examination and has been granted proper authorization for such a statement."That's not even going into the fact that advocating the overthrow of the government is against the sedition laws of the country (which, for some reason, the government seems completely unwilling to enforce.)
But of course for the regressive left anything goes.
