Meet Mary Elizabeth Tyler. Referred to as "the heartbeat of the Klan" during a Congressional investigation of the group's rise in the 1920s, Tyler used her skills as a publicist to rebrand the KKK and launch the Women's KKK, leading to millions joining. Tyler, and her business partner, helped the Klan gain national acceptance until scandals, including a brutal murder of a young woman, revealed the truth behind the leaders of the KKK.
