U.S. officials now believe Iran's new supreme leader is alive and communicating with Mohsen Razai U.S. officials believe that Mohsen Razai is in regular contact with Iran's Supreme Leader Mujtaba Khamenei and that the two have been communicating since Razai received the letter from Vice President J. Di Vances, according to the Washington Post. This is the main reason why the letter was sent to the person closest to him at the moment, the secretary of Iran's Supreme National Security Council, Mohsen Razai. The letter is actually a message directly to the Iranian Supreme Leader Mujtaba Khamenei.
