Update: Joe Rogan's unexpected offer to host an unscripted debate between Biden and Trump may have altered Sanders' thinking sources have reported to me. Sanders, a former guest on Joe Rogan's show, likely has no interest in another such interview. One source mentioned tension after the show had recorded, with at least one staff member indicating "several punches were thrown though none landed." So far, it has not been indicated to me if JR or BS was the attacker. I will keep you all updated as I learn more.
