Evangelist Billy Graham continues to undergo physical therapy to rebuild his strength after a series of intestinal bleeds last week.
Hospital officials say Graham has been taking walks around his hospital unit and interacting with staff.
The 88-year-old preacher has been in the hospital since a bleeding episode last Saturday. He had two more bleeds in the following days but a physician cauterized a lesion in the colon on Wednesday. He hasn't had any bleeding since.
