"Iran has very good access to the whole world to carry out strikes against America," Mahmoud-Reza Sajjadi told reporters in Moscow, according to Bloomberg News.

Gingrich's comments essentially echo those of Rick Santorum, who has used the issue of Iran to criticize his Republican opponents.

“Once they have a nuclear weapon, let me assure you, you will not be safe, even here in Missouris,” Santorum said at a campaign stop last Friday in Missouri. “These are folks who have been and are at war with us since 1979. This is a country that has killed more troops in Afghanistan and Iraq than the Iraqis and Afghans.”

Gingrich made no mention of Santorum — riding high after a sweep of the Missouri, Minnesota and Colorado contests Tuesday night — or chief rival Mitt Romney during his brief remarks in Cleveland.

The stop was Gingrich's only planned campaign appearance over the next two days, a relative lull in the hectic campaign season. Gingrich's campaign did announce Wednesday that they would head to Georgia — the state Gingrich represented in the House — to campaign next week. Romney was already campaigning in Georgia Wednesday; the state represents the largest number of delegates available in the crucial Super Tuesday slate of primaries.
