Washington – Former Vice President Joe Biden has said he has not taken a test to measure his cognitive abilities, ignoring the suggestion as President Trump and his campaign continue to question his mental fitness to exercise his skills. functions.

“No, I didn’t do a test. Why the hell would I take a test? Come on, man, ”Biden told CBS News correspondent Errol Barnett in an interview that aired in full Thursday at the National Association of Black Journalists and National Association of Hispanic Journalists convention. “It’s like saying that before you enter this program, you take a test to find out whether you are taking cocaine or not. What do you think, eh? Are you a drug addict? “

Biden’s campaign did not respond to requests for further clarification from CBS News.

It is not known what cognitive test Mr. Trump took, although he claimed in an interview in July that he “spent” it. In January 2018, the president took a test called the Montreal Cognitive Assessment, which is not an IQ test, but is used to detect signs of dementia or other cognitive problems.

“If he can’t figure out the difference between an elephant and a lion, I don’t know what he’s talking about,” Biden said in the interview with Barnett, an apparent reference to the part of the test where the subject is asked. identify animals. Biden also said he was eager to prove his mental sharpness during the debate over Mr. Trump.

“I’m so looking forward to the opportunity to sit down with the president or stand with the president and the debates,” he said. “I’m very willing to let the American public judge my physical and mental form and, you know, pass judgment on who I am.”
