Santorum's campaign said Friday that Bella had been taken to an undisclosed hospital. The 3-year-old has the rare genetic condition Trisomy 18 and was hospitalized earlier this year with pneumonia.

Santorum's campaign did not say why she was hospitalized. The former Pennsylvania senator is spending a few days off the campaign trail for Easter.

Bella's condition typically proves fatal. Santorum often says she wasn't expected to live past her first birthday. He often carries a photo of her on the campaign trail.
