David Leonard hosts Larry Tye to discuss his new biography of U.S. Senator Joe McCarthy.

From 1950 to 1954, McCarthy destroyed many careers and even entire lives, whipping the nation into a frenzy of paranoia. Based on the first-ever review of his personal and professional papers, medical and military records, and recently unsealed transcripts of his closed-door congressional hearings, in "Demagogue" Tye reveals a human being whose chaotic, meteoric rise is a lesson for us all.

This conversation is presented in partnership with American Ancestors (NEHGS). The event is free to the public.
