Elin Hilderbrand on finding the "emotional truth" in "Summer of '69"
50 years ago this summer, Americans saw some monumental highs and lows. On July 18, 1969, then-Sen. Ted Kennedy drove his car off a bridge on Chappaquiddick Island in Massachusetts. Just two days later, Apollo 11 astronaut Neil Armstrong stepped onto the moon as the world watched in awe. Then in August, music fans and hippies descended on upstate New York for the three-day Woodstock music festival. Author Elin Hilderbrand weaves these events into her new book, "Summer of '69." Hilderbrand joins “CBS This Morning” to discuss the novel.
