U.S. Rep. Gabrielle Giffords has been taken off a ventilator and is breathing on her own through a tracheotomy tube, the University Medical Center of Tucson, Arizona announced Saturday.
Surgeons on Saturday also inserted a feeding tube so the congresswoman could get nutrients.
In addition, one other person injured last Saturday's Arizona shooting - James Tucker, 58 - was released from the medical center on Saturday, leaving three people still at the hospital.
