Gabby Giffords's road to recovery – Sanjay Gupta looks at her progress

Gabrielle Giffords, the Arizona congresswoman who was shot in the head during a shooting rampage in January, appeared in her first television interview late Monday night. Giffords and her husband Mark Kelly talked with ABC News' Dianne Sawyer about the highs and lows of her recovery. Giffords could clearly understand the questions put to her, but was able to respond only in simple words.

Christine Romans and Carol Costello talk with CNN Chief Medical Correspondent Dr. Sanjay Gupta about Giffords' current medical state.
