DELRAY BEACH, Fla. (AP) — Republican Mitt Romney is refusing to say if he would be open to one-on-one talks with Iran if elected president.

The presidential candidate was asked about Iran while officiating a coin toss at a flag football game in Florida between reporters and his senior campaign aides. Romney, who was taking a break from debate preparations, also declined to say how he was feeling about the Monday night debate with President Barack Obama or about a new poll showing a close race.

The White House on Saturday said Obama's administration is prepared to talk one-on-one with Iran to find a diplomatic settlement to the impasse over Tehran's reported pursuit of nuclear weapons. Romney has said he would tighten sanctions on the country, though he has not specified how.
