Graham spokesman Mark DeMoss says they hope to have the Rev. back home in a day or two.
Graham has suffered from various ailments over the years, including macular degeneration and hearing loss. He was diagnosed with prostate cancer in 2007.
The celebrity reverend is known for counseling presidents, leading worldwide crusades and writing bestsellers.
These days, due to his age and health concerns, Graham rarely leaves his home in Montreat, North Carolina.
Evangelist Billy Graham, who turned 95 on November 7th, is back in the hospital due to respiratory congestion issues, reports the Associated Press.
