The original quote came from an April 2007 interview with the Associated Press. Romney said in that interview he backs a broad strategy to defeat Islamic jihadists and that it's "not worth moving heaven and earth" for one person. Romney said catching bin Laden would make the country safer by a "small percentage" -- he added, a "very insignificant increase in safety." Romney's argument was that somebody else would replace bin Laden at the helm of Al Qaeda.
None other than Sen. John McCain, the 2008 GOP nominee who is now defending Romney on the issue, criticized him for the April 2007 statement.
