Those helping Rep. Gabrielle Giffords in her rehabilitation process say she's now walking more with assistance and able to talk in complete sentences.
Doctors gave new details on the Arizona congresswoman's condition in a press conference Friday.
Giffords has no memory of the assassination attempt against her that left six people dead and 12 others wounded, but knows she was shot.
"She has been told both by her husband and by us, and I think she understands," said neuroscientist Dr. Dong Kim.
Doctors also said she's improved so much that she may be able to see her husband Mark Kelly's space shuttle launch in April.
Giffords' breathing tube was removed last week. She's also showing emotions, including smiles when she makes progress.
