 Trump has finally announced a couple of rallies next week. Biden is holding a campaign rally in Madison, Wisconsin, on Friday. More significantly, while he's there, the president will sit down for an interview with ABC News anchor George Stephanopoulos. This is a pretty rare thing for Biden, certainly compared to past presidents. An unscripted interview is another high profile test of his cognitive abilities. And depending on how it goes, the interview could quiet the calls for Biden to step aside or make them grow louder.
