Gabby Giffords' inspiring first interview

It's been 10 months since the fatal Tucson shooting that left 6 people dead and Congresswoman Gabby Giffords just barely hanging on. In the intervening time, Giffords has undergone what her doctors call a "miraculous" recovery. Diane Sawyer interviewed Giffords about her victories, her struggles and her memories for a special edition of "20/20," which aired last night. What follows is an inspiring and heartrending show of resilience in the face of incredible challenges.
