The interview will most likely garner huge public interest. Giffords was shot in the head in January in an attack that killed six people. Despite her grievous injuries, she has managed to regain much of her motor skills. It is unknown how much Giffords will speak during the interview. Although her doctors say she can understand people, they have said she has difficulty forming words.

ABC has dozens of hours of tape of her rehabilitation and recovery and Giffords will appear on camera during the special, however, Mark Kimble, Giffords’s spokesman, said “The congresswoman has not decided whether she will participate in an on-camera interview with ABC.” He said Kelly will definitely be interviewed, but that Giffords will decide closer to the interview date based on the progression of her recovery. 

Since the shooting, Giffords has made only one public appearance, but it was a show-stopper. She was greeted with a standing ovation when she appeared in Congress last month during the debt ceiling vote.
