Iran has elected former nuclear negotiator Hassan Rouhani as the new president, replacing Mahmoud Ahmadinejad. Rouhani is considered a moderate compared to the other candidates. He took just over half the vote in a national turnout of 72 percent. Rouhani has called for greater engagement with Western countries, while urging respect for Iran’s right to nuclear energy. On Sunday, White House Chief of Staff Denis McDonough called Rouhani’s election “a potentially hopeful sign.” We’ll have more on the Iranian elections after headlines.
