"I know Newt Gingrich at the end of the ad says I approved this message, well let me just say, I didn't approve that message," Huckabee said in an interview Friday on Fox News.
The former governor of Arkansas said his words were "taken out of context" and were also " deceptive" because he was not referring to Romney, one of his 2008 primary rivals.
"That spot, which was back in December of 2007, never mentioned Mitt Romney by name, it never said anything about Mitt Romney. It was a general statement," Huckabee, has not endorsed anyone so far in the 2012 presidential race, and says he doesn't plan to do so.
Earlier in the week, the Gingrich campaign ran into trouble with another campaign ad. U.S. Senator Marco Rubio, who has also not endorsed a candidate in the presidential primary, told The Miami Herald's Marc Caputo, that Gingrich should take down a Spanish language radio ad that described Romney as " anti-immigrant." The Gingrich campaign soon pulled the ad to edit out that line, out of "respect" for Rubio.
But that won't happen with the ad featuring Huckabee. Gingrich spokesperson R.C. Hammond says the campaign does not plan on pulling the Huckabee clip.
"Huckabee has said he hasn't endorsed anybody but that doesn't change what he said," Hammond told reporters.
"Speaker Gingrich and his political cronies are desperate to distract from his record of failed and unreliable leadership, and voters won't be fooled." said Andrea Saul, a Romney spokesperson, said in an earlier statement.
