Harvard Law professor, Alan Dershowitz, who didn’t even vote for Trump in the election thinks it’s disgusting that the liberals are claiming that Donald Trump has a mental disorder and is mentally unfit for office, reports Fox News.

Dershowitz is a Democrat who supported Hillary Clinton in the 2016 election and even he thinks that the liberals have gone a step too far with the left’s recent cry to use the 25th amendment to remove President Trump from office.

The professor called these cries “very dangerous,” and said that they were worse than trying to criminalize Trump.

“There’s only one thing worse than trying to criminalize political differences and that’s trying to psychiatrize them,” he said. “These psychiatrists who are trying to diagnose without having even met the man. That’s what they did in Russia.”

Yale University psychiatrist Dr. Brandy X. Lee told the Washington Examiner that several Democratic senators and one Republican senator met with her after she published analysis questioning Trump’s mental health.

However, Lee’s statements seem to be violating the “Goldwater Rule,” which is an ethical standard set forth by the American Psychiatric Association regarding evaluating politicians or people they have not met. The same kind of criticism was occurring to Barry Goldwater when he was running for President in 1964, hence the name of the rule.

“How dare liberals… try to undo democracy by accusing a president of being mentally ill without any basis?” Dershowitz asked of those citing Lee and others.

Dershowitz said the 25th Amendment — ratified in 1967 and delineating presidential succession — does not apply in this case.

He does say that maybe it applied in cases like with Ronald Reagan, who was proven to have developed Alzheimer’s near the end of his term but would have had to be invoked by his Vice President, George Bush.

Dershowitz said in Trump’s case, that duty would fall to Mike Pence and then require a two-thirds vote of both houses of Congress to remove him, which is a scenario that is very unlikely to happen.
