 But the first elected Democrat to call for Biden to step aside is not convinced. The need for him to step aside is more urgent tonight than when I first called for it on Tuesday. We're wasting our time defending him when we should be pointing out the shortcomings, the failures, the wrongdoing of Donald Trump. Still other Democrats are defending Biden's performance. Now, since he's under such a microscope, all of us looking for those flubs, what would be a normal part of any conversation is considered to be a national security problem.
