On June 2, 2004, “U.S. intelligence officials told the New York Times that [Iraqi National Congress leader Ahmed] Chalabi had given American state secrets to Iran, including news that ‘the United States had broken the secret communications code of Iran’s intelligence service,’ thereby destroying Washington’s most valuable source of information about Iran. Chalabi consistently denied having given any intelligence to Iran, maintaining that the allegations were a CIA smear.”
