Where did you see that?
On June 30th, Biden was asked by a reporter if he had taken a cognitive test. "I've been tested and I'm constantly tested," Biden said. "Look, all you got to do is watch me, and I can hardly wait to compare my cognitive capability to the cognitive capability of the man I'm running against."
During an interview on August 6th, former Vice President Joe Biden said that he had not taken a cognitive test and attacked the question as unfair, likening it to being asked if he was a "junkie."
"No, I haven't taken a test. Why the hell would I take a test?" Biden said in an interview with the National Association of Black Journalists and National Association of Hispanic Journalists. "Come on, man. That's like saying you, before you got on this program, you take a test where you're taking cocaine or not. What do you think? Huh? Are you a junkie?"
