Episode 200-Trump's Arraignment and 37 Count Indictment by the Biden DOJ.  The charges: taking classified documents, admitting he didn't declassify all of them, discussing some of them, being careless and sloppy with the storage of them in various Mar-a-Lago rooms, trying to hide some of the boxes from the FBI then suggesting to his lawyer they could just lie to the FBI about what they had.  How serious are these charges?  Should Trump drop out of the presidential race?
