 President Biden has hunkered down and he's been at Camp David. Took a week off from the presidency. I've never seen anything like this before. It isn't unusual for a president to take some time off as the time grows near for a debate. Presidents get rusty during their time in office and Biden is not used to being challenged on policy decisions or opinions. He stays cocooned in the White House or at one of his mansions in Delaware, away from the press corps. He rarely gives interviews.
