'Could do something catastrophic': Clinical psychologist issues grave warning about Trump

A clinical psychologist said on Wednesday that President Donald Trump's cognitive decline has become clear, and it's putting Americans at "grave risk."

Dr. John Gartner, clinical psychologist and former Johns Hopkins professor, who unofficially diagnosed Trump with "malignant narcissism" during his first term, discussed Trump's cognitive decline on a new episode of "The Daily Beats Podcast" with host Joanna Coles, the outlet's chief content officer.

Gartner pointed out several signs of Trump's cognitive decline, from the way he seems to make up endings of words that he can't fully remember to the way his mind makes concatenations like a "stone skipping along the water."

While his condition seems under control for now, Gartner warned that Trump's already "impulsive and erratic behavior" could get worse.

"It's so impulsive and erratic, and this guy has the nuclear football," Gartner said. "This is really someone who could wake up in a state of complete confusion and their kind of irritation and do something catastrophic. And no one is going to stop him."

Gartner said the eight recent boat strikes the U.S. military has carried out are a sign of Trump's worsening condition.

"It's a blatant violation of our law of international law," Gartner said. "It's going to get worse."
