How America’s first ladies balanced public and private life

A new book takes an up-close look at the women who have called the White House home. "First Ladies: Presidential Historians and the Lives of 45 Iconic American Women" is a culmination of a year-long series by C-SPAN. Judy Woodruff talks to book editor and C-SPAN co-CEO Susan Swain about the influence they wielded behind the scenes and what the role of a “first man” might look like.
