WASHINGTON — Rick Perry isn't the only one to have an "oops" moment in the Republican presidential contest.

An article on Newt Gingrich's official website is headlined "A Tale of Three Wives: Life on the Campaign Trail."

It's a short, feel-good piece about Gingrich's wife, Callista, and the wives of Perry and Jon Huntsman.

But the story might remind viewers that Callista is Gingrich's third wife. His divorces from the first two are a subject of campaign conversation.

The religious network CBN News wrote the article. The campaign posted it, headline and all, on the Gingrich website. A Gingrich campaign spokesman says such postings are commonplace.
