Full Bio: Ted Kennedy and Chappaquiddick

In this July 19, 1969 file photograph, crowds watch as U.S. Sen. Edward Kennedy's car is pulled from water at the Dyke Bridge in Edgartown, Mass.

For this month's installment of Full Bio, we speak with John A. Farrell, author of the new biography, Ted Kennedy: A Life, about the former Massachusetts senator and presidential candidate. On Day three, we speak about Kennedy's personal demons and controversies, including his excessive drinking, and the infamous Chappaquiddick incident which resulted in the death of Kennedy's acquaintance, Mary Jo Kopechne.
