And Ms Giffords's mother has said the Democratic congresswoman has made remarkable progress since the 8 January attack at a constituency event outside a store in Tucson.
Gloria Giffords told friends in an e-mail that her daughter had scrolled through photographs on her husband's iPhone and had begun to look at "get well" cards and pages from a large-print book while in her hospital room, the New York Times reported.
