Since suffering a gunshot wound to the head in January of last year, Congresswoman Gabby Giffords and her husband, astronaut Mark Kelly, have largely shunned the spotlight. But now the couple is opening up about her recovery process in the new book “Gabby: A Story of Courage and Hope” and an interview with Diana Sawyer on ABC’s “20/20.” New York Magazine contributing editor Steve Fishman and Arizona Public Media senior political reporter Christopher “Buzz” Conover discuss what the future holds for the Arizona Democrat.
