Republican presidential candidate Rick Santorum is expected to announce suspension his campaign, according to reports.
Santorum has reportedly spoken to GOP presidential front-runner Mitt Romney and an additional source has said that Santorum, his wife, and campaign manager held a conference call with staff April 10, advising them not to grow discouraged.
"We are going to stay involved and stay active in the next couple of months," Santorum said, according to the source.
Another source said family and political reasons are major factors for Santorum's decision, adding that the candidate will lay out explicit reasons in the press conference.
The announcement comes after the former Pennsylvania senator took a four-day break from the campaign to spend time with his hospitalized three-year-old daughter, who suffers from a serious chromosomal condition that interferes with development.
His daughter, Bella, was released from the hospital late Monday night.
Santorum launched his presidential bid on June 6.
