Democratic presidential candidate Joe Biden has mocked an interviewer who asked him if he would take a cognitive test, and also dismissed Donald Trump’s challenge to do so.
“Why the hell would I take a test?” the 77-year-old politician asked, during a Tuesday Yahoo News interview after confirming that he has not taken one. Biden then used his catchphrase “come on, man” to mock the very idea, adding that it is like asking the interviewer, Errol Barnett, if he has been taking cocaine before the interview.
