From the NYT:
Her condition was unknown. She was taken to University Medical Center in Tucson, the trauma center for the area, about 10 miles away. NPR and CNN reported that she had been killed, but Darci Slater, a hospital spokeswoman, said that Ms. Giffords was in surgery....
Correction: January 8, 2011
An earlier version of this article misstated Gabrielle Giffords's condition. While several news reports had said she had died on the scene, a hospital spokeswoman said that the congresswoman was undergoing surgery.
