Nuclear program of Iran
U.S. President Obama reportedly sent a letter dated 20 April 2010 to President Lula of Brazil, in which he outlined a proposal of fuel swap. While expressing skepticism that the Iranians would now be willing to accept such a deal, having provided "no credible explanation" for the previous deal's rejection, President Obama wrote "For us, Iran’s agreement to transfer 1,200 kg of Iran’s low enriched uranium (LEU) out of the country would build confidence and reduce regional tensions by substantially reducing Iran’s LEU stockpile." Turkish Prime Minister Recep Tayyip Erdogan received a similar letter. A senior U.S. official told the "Washington Post" that the letter was a response to Iran's desire to ship out its uranium piecemeal, rather than in a single batch, and that during "multiple conversations" U.S. officials made clear that Iran should also cease 20% enrichment; however, the official stated "there was no president-to-president letter laying out those broader concerns".
President of Iran
The first Iranian presidential election was held on January 25, 1980 and resulted in the election of Abulhassan Banisadr with 76% of the votes. Banisadr was impeached on June 22, 1981 by Parliament. Until the early election on July 24, 1981, the duties of the President were undertaken by the Provisional Presidential Council. Mohammad-Ali Rajai was elected President on July 24, 1981 and took office on August 2. Rajai was in office for less than one month because he and his prime minister were both assassinated. Once again a Provisional Presidential Council filled the office until October 13, 1981 when Ali Khamenei was elected president.
