Trump, Biden Question Each Other's Fitness for Office Steve Herman WHITE HOUSE - U.S. President Donald Trump and his election challenger, former Vice President Joe Biden, on Thursday accused each other as being unfit for office. Trump, who is 74, characterized his 78-year-old opponent as "shot" and "weak" and alleged that "something is off" with Biden's mental state. Speaking at a political rally in the Midwestern state of Wisconsin, 47 days before the election, the Republican president added that Biden "doesn't know he's alive." Biden, in Pennsylvania, criticized Trump as being "totally irrational" in his handling of the coronavirus pandemic and discouraging people from following the scientific advice of the government's own health experts. "You've got to level with the American people -- shoot from the shoulder," said Biden. "The president should step down." If Trump had acted earlier, he would have saved thousands of American lives from the coronavirus, according to Biden. "He knew it and he did nothing," Biden said. "It's close to criminal." "I've been doing this a long'¯time.'¯I never, ever thought I would'¯see such a thoroughly, totally'¯irresponsible administration," said Biden. .
