LANCASTER, Pa. (AP) - Now that he's dropped out of the Republican presidential race, what's next for Rick Santorum? The former senator didn't have much of an answer Tuesday night at a forum in Pennsylvania, other than to say that he'd like to get some sleep.

Santorum spoke at an event at Lancaster Bible College, just hours after he'd announced an end to his campaign for president.

The event was billed as a "conversation on faith, family and American values" with James Dobson, the founder of the evangelical Christian group Focus on the Family.

In addition to asking him what's next, Dobson questioned the former Pennsylvania senator about his campaign and other memorable times in his public and personal life.

Santorum says he's taken five days off from the road since announcing his candidacy last June in Somerset, Pa.
