ABC News’ Matt Stuart Reports: Former Massachusetts Gov. Mitt Romney unveiled a new radio ad Monday, continuing his call for the United Nations and Columbia University to withdraw their respective invitations to Iranian President Mahmoud Ahmadinejad.
The ad, which begins airing today in Iowa and later this week in New Hampshire and Florida, touts Romney’s refusal as Governor to provide a police escort to former Iranian President Mohammad Khatami when he spoke at Harvard University, saying "Romney called the invitation a ‘disgrace.’"
All the major Republican candidates for president have issued statements against the Iranian leader, but the ad argues that Romney "is leading the opposition" to Ahmadinejad.
Republican candidate former Sen. Fred Thompson, R-Tenn., told Bill Bennett’s "Morning in America" talk radio show Monday morning that if he were running the country, he would deny Ahmadinejad entry into the United States.
