Khamenei, in a recent speech, revealed that Obama said he endorsed Iran's right to have a nuclear program while President Mahmoud Ahmadenejad was still in power.
“The issue of negotiating with the Americans is related to the term of the previous [Ahmadinejad] government, and to the dispatching of a mediator to Tehran to request talks,” Khamenei said in a recent speech translated by the Middle East Media Research Institute (MEMRI).
“At the time, a respected regional figure came to me as a mediator and explicitly said that U.S. President [Obama] had asked him to come to Tehran and present an American request for negotiations,” Khamenei disclosed. “The Americans told this mediator: ‘We want to solve the nuclear issue and lift sanctions within six months, while recognizing Iran as a nuclear power.’”
“I told that mediator that I did not trust the Americans and their words, but after he insisted, I agreed to reexamine this topic, and negotiations began,” Khamenei added.
