ASHEVILLE, N.C. - Doctors say they're encouraged by the Rev. Billy Graham's improvement as the evangelist recovers from pneumonia but haven't set a date for his discharge from a North Carolina hospital.

Officials at Mission Hospital in Asheville say Graham also is progressing in his program of physical therapy and is walking more in the private corridor outside his room.

Graham was admitted Wednesday night after suffering from congestion, a cough and slight fever that was later diagnosed as pneumonia.

The 93-year-old evangelist was visited over the weekend by his son, Franklin Graham, and daughters, Gigi Graham and Anne Graham Lotz and her two daughters. He watched his pastor, Dr. Don Wilton, preach on television as he does at home each Sunday.
