Former Trump White House attorney Ty Cobb on Thursday explained why he believes Donald Trump’s mental acuity has “definitely accelerated” in its decline since his first term, when Cobb served in the White House.

Cobb, now a vocal critic of his former boss, told MS NOW’s Ari Melber that recent controversies — including Trump’s attacks on the late filmmaker Rob Reiner and former special counsel Robert Mueller and his feud with Pope Leo XIV — “just shows you how crazy this man is.”

“When I was there, his narcissism would be on display because he would passionately want to do something that seemed out of bounds but people like Gen. [John] Kelly and Gen. [Jim] Mattis, Nikki Haley, were there to talk him out of it,” he explained.

But “they don’t have those guardrails there today,” he lamented.

Cobb argued there “should be some concern that people are using this, using his incapacity, to manipulate decisions,” suggesting that Israeli Prime Minister Benjamin Netanyahu did that “in connection with the decision to go into Iran.”

Trump’s “vocabulary has shrunk, he’s resorted to profanity and threats, totally impulsive,” he added.

Cobb also drew a stark contrast between former President Joe Biden’s “benevolent grandpa losing his memory” and Trump’s “malignant narcissism.”
