Trump confuses the name of his doctor when bragging about taking a cognitive test

Former President Donald Trump on Saturday confused the name of his former White House physician just moments after he said President Joe Biden should take a cognitive test.

The mix-up happened as Trump bragged that he had "aced" a cognitive test. Trump also criticized Biden, saying, "I think he should take a cognitive test like I did."

"I took a cognitive test, and I aced it. Doc Ronny — Doc Ronny Johnson," Trump said, confusing the name of his White House physician, Dr. Ronny Jackson, now a member of the House. "Does everyone know Ronny Johnson, congressman from Texas? He was the White House doctor.”

Trump continued, bragging about having gotten "every question right" on the cognitive test Jackson administered, apparently unaware that he had fumbled his name.

Jackson administered the Montreal Cognitive Assessment to Trump in 2018.

A spokesperson for the Trump campaign did not immediately respond to a request for comment Sunday evening.

Trump has mixed up the names of prominent officials and politicians before. In January, he confused GOP presidential rival Nikki Haley with Rep. Nancy Pelosi, D-Calif., when he was talking about the Jan. 6 attack on the U.S. Capitol. Trump has referred to Hungarian Prime Minister Viktor Orbán as the leader of Turkey, and he has switched Biden's name with that of former President Barack Obama, which Trump defended, saying he did it "sarcastically."

Trump, who turned 78 years old Friday, frequently tried to paint Biden, 81, as mentally incompetent.

The Biden campaign hit back Saturday, posting a clip of Trump's mix-up on X. The post got more than 18,000 likes.
