What happens when there are gaps in the historical records of some of America’s most seismic political events? How do historians try to piece together those mysteries? And how might these question marks help to contextualize the missing Secret Service texts from January 6th?  Heather and Joanne discuss the mysteries surrounding the 1804 Burr-Hamilton Duel, the 1865 Hampton Roads Conference, and the 1920 Wall Street bombing.  Join CAFE Insider to listen to “Backstage,” where Heather and Joanne chat each week about the anecdotes and ideas that formed the episode.
