(CNN) -- GOP presidential candidate Rick Santorum will take a break from the campaign trail Monday as his 3-year-old daughter remains hospitalized, his campaign announced Saturday.
"Senator Santorum will not hold any public campaign events on Monday so that he and Karen can remain in the hospital with their daughter Bella," communications director Hogan Gidley said in a statement. "The entire Santorum family is incredibly grateful for the outpouring of prayers and support."
Santorum had not announced public events, but his campaign had previously said he would resume campaigning Monday after taking the Easter weekend off.
The campaign announced Friday that his daughter Isabella was hospitalized for the second time this year. She suffers from a chromosomal condition called Trisomy 18 and was last hospitalized in January for pneumonia.
His campaign on Saturday issued a revised schedule with events to be held Tuesday through Friday.
Pennsylvania is Santorum's home state and one of several to vote April 24. A win there is seen as critical for Santorum, especially as the delegate math is increasingly stacked against him.
