Since Saturday, Gabrielle Giffords has been in a Tucson hospital for treatment of wounds from a bullet that passed through her brain. The Democratic Congresswoman has been able to follow simple commands like wiggling her toes or showing a specific finger. Neurosurgeon Michael Lemole says she's been giving CAT scans daily. Gifford's husband, astronaut Mark Kelly thanked well-wishers for their "unbelievable outpouring of support." Jim Nintzel, senior writer for the Tucson Weekly, has covered Giffords since she entered politics in the year 2000.
