Santorum to South Carolina next week

Former Sen. Rick Santorum (R-Pa.) will travel to South Carolina next week, a state that holds a key presidential primary contest every four years.

The conservative's political action committee announced the trip Tuesday, saying that he will take a two-day swing through the state next Monday and Tuesday.

Santorum, who lost to Sen. Bob Casey (D-Pa.) in 2006, has been open about his desire to explore a 2012  presidential bid.

The ex-senator has not yet announced the cities he will visit or the events he will attend.
