FILE - In this June 6, 2011 file photo, former Pennsylvania Sen. Rick Santorum holds his daughter Isabella before announcing he is entering the Republican presidential race, on the steps of the Somerset County Courthouse in Somerset, Pa. Santorum canceled his morning campaign events, Sunday, Jan. 29, 2012, and planned to spend time with his hospitalized daughter, Bella. Isabella Santorum has Trisomy 18, a genetic condition caused by the presence of all or part of an extra 18th chromosome.

BOCA RATON, Fla. — Republican presidential candidate Rick Santorum says his daughter Bella remains in the hospital with pneumonia but is recovering after a rough 36 hours.

Santorum spoke with Florida supporters by telephone from Bella's hospital room and said he hopes she can go home in the next few days. Florida has its primary Tuesday, and Santorum canceled campaign stops there Sunday to stay with his 3-year-old daughter.

Bella has a genetic condition known as Trisomy 18. The condition typically proves fatal and Santorum often says his daughter wasn't expected to live past 12 months.

The former Pennsylvania senator says Bella is awake and alert and back to being a "beautiful, happy girl."
