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.
