The Pentagon bought tens of thousands of copies of a new book called Operation Dark Heart in order to destroy them on national security grounds. The author, Lieutenant Colonel Anthony Shaffer, explains why, and tells what he witnessed in the war in Afghanistan. Then, Jett Williams, Hank Williams’ daughter, talks about a new collection of the country music pioneer's recordings. Also, Joseph O’Neill talks about his grandfathers—one Turkish, one Irish—who were both imprisoned for suspected subversion during World War II. Plus, award-winning historian Ron Chernow discusses George Washington.
