Huffington Post editor-in-chief Arianna Huffington voiced her criticism of the spot Monday, calling it "one of the most despicable things you can do."
“I think it’s one thing to celebrate the fact that they did such a great job. It’s one thing to have an NBC special from the Situation Room,” the media mogul said on “CBS This Morning." “All that, to me, is perfectly legitimate. But to turn it into a campaign ad is one of the most despicable things you can do.”
The video, released Friday, features Bill Clinton touting President Barack Obama's role in directing the raid that resulted in bin Laden's death last May. It then questions whether Romney would have made the same call, according to Fox News.
Obama campaign adviser Robert Gibbs, the former White House press secretary, told Fox News that the ad was "fair game."
Romney adviser Ed Gillespie acknowledged it's legitimate for Obama to be proud of the bin Laden raid, but objected to the implication that Romney would not have made the same decision. Gillespie called the move "divisive."
"I think most Americans will see it as a sign of a desperate campaign," Gillespie said on NBC's "Meet the Press."
Obama's 2008 opponent, Arizona Sen. John McCain, issued a scathing statement in which he accused Obama of playing politics with the bin Laden killing and "diminishing the memory of September 11th."
GOP strategist Nancy Pfotenhauer told Fox News the video "politicizes something that shouldn't have been politicized" and signals how "nasty" the 2012 campaign will become.
