Gadhafi was killed in his hometown of Sirte on Thursday, according to a spokesman for the U.S.-backed revolutionary movement that overthrew him.
Images and video from a mobile phone of what appeared to be Gadhafi's bloodied body were released by Agence France-Press and Al Jazeera.
As the former Massachusetts governor was walking away, a reporter asked if President Obama "deserves a measure of credit" for the death of the deposed Libyan leader.
You can hear Romney say, "Sure," as he continues to walk, but it is unclear if he is directly responding to the reporter's question.
