GOP presidential candidate Rick Santorum's campaign says his hospitalized daughter is recovering and could leave the hospital soon.

Santorum spokesman Hogan Gidley said Monday that 3-year-old Bella could be released from a northern Virginia hospital by the end of the day.

She was hospitalized Friday. Her father did not campaign Monday so he could be with his daughter, who suffers from a rare genetic condition.

Bella was hospitalized earlier this year with pneumonia. Her father faces an uphill battle against front-runner Mitt Romney in the race for the Republican presidential nomination. Santorum often says Bella wasn't expected to live beyond her first birthday.
