Rick Santorum is offering a tongue-in-cheek apology to anyone who has seen the recent snapshot of him sunbathing poolside at a resort in Puerto Rico.

The Republican presidential candidate appears shirtless and shoeless in light-colored shorts while taking a break from campaigning in the U.S. commonwealth. The photo appeared on a blog and began showing up on various websites. 

In an interview Friday with Chicago radio station WIND, Santorum said he probably should lose 15 or 20 pounds.

Santorum tells WIND, "I apologize to all of us, because I'm sure it's not a pretty sight."

Puerto Rico's Republican primary is set for Sunday. Santorum returned from a visit to the island to campaign in Illinois, which has its primary on Tuesday.

In 1996, Romney Led NYC Search For Runaway Teen

When Mitt Romney's supporters hear critics describe him as aloof, they point to Romney's decision to lead the search for a missing teenage girl in summer of 1996.

Romney headed the venture capital firm Bain Capital at the time. Romney received a frantic report from a fellow executive who said his 14-year-old daughter had gone missing in New York City.

Romney shut down the firm, opened a "command center" at a hotel near LaGuardia Airport, and enlisted a small army of volunteers to comb the city. After local televisions picked up the story, the girl was found safe in a New Jersey home.

Romney says the incident -- featured in campaign ads in 2007 and in the current GOP presidential contest -- bolstered his faith in the generosity of people.
