Rep. Giffords Breathing on Her Own After Attack

TUCSON, Ariz. — U.S. Rep. Gabrielle Giffords is breathing on her own as she continues to recover from her head wound sustained in Saturday's shooting.

Doctors have left a breathing tube in Giffords to protect her airway, but the Democratic congresswoman is drawing breaths on her own, said Dr. Michael Lemole, her neurosurgeon. She's alert and responding to doctors.

Six people are still hospitalized after the shooting Saturday at a Tucson grocery store. The attack killed six and injured 14 others.

Giffords, a three-term Democrat, was gravely wounded. A federal judge was among those killed.
