Vance contacts Iran's security chief in an attempt to revive negotiations US Vice President J. Dee Vance reached out to Iran's security chief in an effort to restart negotiations, the Wall Street Journal reported Wednesday. According to the paper, Vance sent a letter to Mosan Razai, head of Iran's Supreme National Security Council, at the behest of US President Donald Trump, one source said. Trump addressed the report Wednesday night, claiming that Vance proposed the initiative and that he had authorized his vice president to proceed as he saw fit. The letter and subsequent exchanges between U.S. and Iranian officials focused on establishing a potential framework for negotiations rather than discussing the specific terms of a peace proposal, the newspaper reported.
