The 41-year-old congresswoman was seated with her husband, astronaut Mark Kelly, as she talked with ABC's Diane Sawyer for an interview that will air Monday. A preview was broadcast Thursday on "World News."
Giffords was wearing a yellow top with gold buttons and dark eyeglasses. Her brown hair has grown out since it was shaved in May for surgery to repair her skull.
When Sawyer asked how she felt, Giffords said, "Pretty good." She also said her recovery was "difficult."
Giffords is recovering from a brain injury she suffered Jan. 8 when a gunman opened fire outside a Tucson, Ariz., supermarket. Six people were killed and 13 were wounded, including Giffords.
