Gabrielle Giffords to resign from US Congress to work on recovery Source: YouTube Gabrielle Giffords, the US Congresswoman who was shot in the head during an attack at a constituency event in Arizona in which six other people were killed last January, has announced that she is stepping down. Speaking slowly and haltingly, the Democrat politician said in a video message released on YouTube on Sunday that she had more work to do on her recovery. "Arizona is my home - always will be," Giffords said on the video, which was interspersed with footage of life in the state, moments from her political career and images of her alongside her husband. A lot has happened over the past year. We cannot change that but I know, on the issues we fought for, we can change things for the better: jobs, border security, veterans," she said. We can do so much more by working together. I don't remember much from that horrible day, but I will never forget the trust you placed in me to be your voice. Thank you for your prayers and for giving me time to recover. I have more work to do on my recovery, so to do what is best for Arizona I will step down this week. I'm getting better every day. My spirit is high. I will return and we will work together for Arizona and this great country. Earlier this month, Giffords returned to the scene of the shooting outside a supermarket in the city of Tucson. Jared Loughner, the man accused of the shootings, is being held in a mental health facility. In May, a federal judge ruled that Loughner, a high school dropout suffering from delusions and hallucinations, was mentally incompetent to stand trial for the shootings.
