Mitt Romney's presidential campaign spiked an ad during the final weeks of the 2012 campaign that would have criticized President Obama's handling of the terrorist attack in Benghazi, a source with knowledge of the ad confirmed to The Hill.

The television spot was created by the Republican National Committee and played off the famous "3 a.m." attack ad that Hillary ClintonHillary Diane Rodham ClintonState Dept: Russia’s allegations about American citizens ‘absolutely absurd’ Trump on possible sit-down with Mueller: 'I've always wanted to do an interview' Election Countdown: Senate, House Dems build cash advantage | 2020 Dems slam Trump over Putin presser | Trump has M in war chest | Republican blasts parents for donating to rival | Ocasio-Cortez, Sanders to campaign in Kansas MORE aired against Obama during the 2008 campaign.

"It's 3 a.m. and your children are safe and asleep, but there's a phone in the White House and it's ringing. Something's happening in the world," a voiceover in the ad says as images of a building burning are shown and gunfire is heard in the background. The ad then displays text that reads: "Security requests denied. Four Americans dead. And an administration whose story is still changing."

"The call came. Americans deserve answers," the final text of the ad reads.

According to the source with knowledge of the ad's creation, the Romney campaign stopped it from airing for fear that it would shift the focus away from the economy.

ABC News first reported the existence of the ad on Thursday.

Republicans have repeatedly criticized Obama and other top administration officials for their handling of the Sept. 11 attack on the Benghazi consulate, which left four people dead, including the U.S. ambassador to Libya.
