US President Joe Biden admitted in a radio interview that he “screwed up” his presidential debate against Republican candidate former President Donald Trump. In a radio interview with WURD that aired on Thursday (July 4) morning, Biden spoke about his record delivering for Black Americans as president. He stuttered occasionally. Asked whether there was any reason for the American people to be concerned after his halting performance in last week’s debate with Trump, Biden demurred. Biden said he had a bad debate, adding that this should not erase what he’s done as president for three and a half years.
