Santorum's Daughter Taken to the Hospital

Rick Santorum's ill 3-year-old daughter Bella returned to the hospital Friday, his presidential campaign said.

"Rick and his wife Karen have taken their daughter Bella to the hospital. The family requests prayers and privacy as Bella works her way to recovery," a Santorum campaign statement said, according to the Associated Press.

The campaign did not provide a reason for her hospitalization. She has the rare genetic condition Trisomy 18, which is typically fatal. Santorum has repeatedly said his daughter was not expected to live past a year.

Bella was previously hospitalized in January for pneumonia, prompting Santorum to temporarily put his campaign on hold. Santorum later said she made a "miraculous turnaround."

According to the Associated Press, Santorum is spending several days off the campaign trail for Easter.

Bella is the youngest of the candidate's seven children.
