Giffords’ doctors balancing role as rock stars

TUCSON, Ariz. -- One is an irrepressible South Korea native who has treated some of the most horrific wartime injuries in Iraq and Afghanistan. The other is a reserved neurosurgeon who happens to be the brother-in-law of television show host Dr. Oz. Together, they have stood in their white lab coats before a gaggle of TV cameras every morning to update the nation about their highest-profile patient to date: Rep. Gabrielle Giffords. It's a role both are still getting used to.
