'More Proof': Stephen Colbert Spots Major Trump 'Cognitive' Warning Signs

Stephen Colbert said Donald Trump’s brain is “broke.”

“We got more proof of that this weekend when he tried to shame Joe Biden into taking a cognitive test,” Colbert said, then rolled a clip of Trump bragging once again about passing a cognitive test of his own years ago.

Just one problem: Trump botched the name of the doctor who gave him that test, referring to Rep. Ronny Jackson (R-Tex.) ― who was White House physician at the time ― as “Ronny Johnson.”

Colbert broke out his Trump impression to mock the former president.

“Doc Ronny Johnson, he gave me the test, then I went home to my beautiful wife Malaria and my two hideous sons, Urkel and Carl’s Jr.,” Colbert said.

“The Late Show” host said that’s not the only warning sign of Trump’s cognitive problems. One Republican lawmaker who attended a meeting with the former president told a reporter that he was “rambling… like talking to your drunk uncle at the family reunion.”

Colbert noted that business leaders who met with Trump likewise complained that he was “meandering” and “doesn’t know what he’s talking about.”
