Update: An earlier version of this post incorrectly stated that three people were killed in a sniper shooting in Tuscon. Six people died when Jared Lee Loughner shot and killed them at close range.

Ten months after a bullet shattered her skull, Rep. Gabrielle Giffords appeared smiling and joking in a preview of an interview with Diane Sawyer to air Monday night on ABC.

On Monday morning on “Good Morning America,” host Sawyer told viewers what to expect from her interview with Giffords and husband Mark Kelly, which will air on the network’s “20/20” news show.

Sawyer’s interview will show footage of Giffords’s recovery process, from lying in a hospital bed unable to speak to learning how to walk again.

In the interview, doctors and caretakers marveled at Giffords’s progress. The Democratic congresswoman from Arizona was shot point-blank in January by a gunman while hosting an outdoor meet-and-greet for constituents in Tuscon. Six people were killed and 13 wounded in the attack.

Sawyer said two things helped Giffords during her continuing recovery: music and her husband. At one point, Sawyer said, Kelly told Giffords, who was agonizing that she had been beaten, “You’re beat up, but not beaten.”
