LANCASTER, Pa.—Rick Santorum didn't reveal much when asked what's next for him, other than to say that he'd like to get some sleep.

Santorum spoke Tuesday night at an event at Lancaster Bible College in front of a crowd of hundreds, 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.

Dobson questioned the former Pennsylvania senator about his campaign and other memorable times in his public and personal life, in addition to asking him what's next for him. Santorum says he took five days off from the road since announcing his candidacy last June in Somerset.
