Psychiatry professors from several Ivy League universities who argue Donald Trump is unfit for the presidency are calling on Congress to take “lawful steps” to remove him from office.

The professors’ letter to Congress, published by The Huffington Post, says the president’s supposed mental “unraveling” is hurting his ability to govern.

“The power of the presidency has accentuated Mr. Trump’s failings with devastating effects,” the letter states. “His psychological isolation — including his tenuous relationship to reality — has led to the dangerous isolation of the United States from the rest of the world.

“Our Constitution has provisions for removing any president who is unable to discharge the duties of office,” it says. “For the sake of our country and the world, we urge our elected representatives to summon their courage so that lawful steps can be taken to end the Trump presidency.”

The letter is signed by Harvard professor Judith L. Herman, Columbia lecturer Robert Jay Lifton, and Yale professor Bandy X. Lee, along University of California professors Dee Mosbacher and Nanette Gartrell, Campus Reform reported.

It’s an extension of a letter sent to former President Barack Obama in late November, in which Dr. Herman, Dr. Mosbacher and Dr. Gartrell expressed “grave concern” over Mr. Trump’s mental stability and suggested the president suffers from Narcissistic Personality Disorder.
