If the mythology of America's founding has a villain - it's the traitor Benedict Arnold. A once-heroic Revolutionary War general who betrayed his country and nearly lost the war for the colonies.
We're talking with bestselling historian Nathaniel Philbrick to piece together the story behind Benedict Arnold and and his betrayal - from his naval battles on Lake Champlain to his complicated relationship with George Washington.
Nathaniel Philbrick's new book is "Valiant Ambition: George Washington, Benedict Arnold, and the Fate of the American Revolution."
Also on the program: an interview with longtime Vermont poet and playwright David Budbill on his work and his struggles with Parkinson's disease.
