A much clearer picture has emerged of how Arizona Rep. Gabrielle Giffords is doing, and it's a comforting look. Two photos of a smiling Giffords were posted early Sunday on her public Facebook page by her aides. Her hair is shorter, but there are few other signs of her gunshot wound to the head five months ago in Tucson. Giffords has been in a Houston rehab facility since Jan. 26, two weeks after the deadly shooting that killed six and injured another 13, including Giffords. Her spokeswoman, Pia Carusone, cautioned that Giffords still has a long way to go in her recovery, but she said Friday that Giffords could be released sometime this month.
