CHARLOTTE, N.C. — A spokesman for the Rev. Billy Graham says the evangelist has generally been weaker since his 95th birthday celebration last month but his vital signs are good.

Spokesman Mark DeMoss said Tuesday that Graham is at his home in Montreat, N.C., and does not appear to be in any imminent danger.

Billy Graham celebrated his birthday in Asheville, N.C., on Nov. 7 surrounded by hundreds of friends and guests. Two weeks after the party, Graham was hospitalized for two days for observation and lung tests. He had been hospitalized in October for pulmonary testing.

Graham uses a wheelchair and has been hospitalized for several health-related issues over the past few years.
