Doctor: Senator responding to voice, touch

Sen. Tim Johnson, who underwent brain surgery Thursday morning, is responding to word and touch, his doctor said.
 
The Democratic senator from South Dakota suffered a brain hemorrhage on Wednesday.
 
Johnson, 59, was in critical condition Thursday morning after surgery, said David Boyd, a spokesman in the nursing supervisor's office.
 
Adm. John Eisold, attending physician at the U.S. Capitol, said Johnson's post-operative recovery has been "uncomplicated."
