 Live from NPR News, I'm Dale Willman. President Joe Biden says he's completely ruled out leaving the presidential race. He's faced criticism for more than a week since his poor performance in last week's debate with presidential challenger Donald Trump. Biden acknowledges that he did not do well and says he had a bad cold and was exhausted during the debate, so wasn't focused well enough. Even when I was answering a question, even when I turned his mic off, he was still shouting it.
