DENVER (AP) - Republican presidential candidate Mitt Romney says he can't imagine calling the killing of a U.S. ambassador a "bump in the road."
His comments Monday were veiled criticism of Obama for his comment in an interview broadcast Sunday.
In an interview with "60 Minutes," Obama said "there are going to be bumps in the road because ... in a lot of these places the one organizing principal has been Islam." Obama was asked about recent events in the Middle East but not specifically about the attack in Libya that killed Ambassador Chris Stevens and three other Americans.
Romney told ABC News that he couldn't "imagine saying something like the assassination of ambassadors is a bump in the road."
White House spokesman Jay Carney called the GOP criticism desperate.
