 Iran's presidential election is heading to a runoff. A hardliner and a reformer are neck and neck after the first count to succeed Ebrahim Raisi, who was killed in a helicopter crash last month. Vote counting continues, but it's already clear neither of the frontrunners has a clear majority, which means a runoff between the reformer, Massoud Pazashkian, and the hardliner, Saeed Jalili, next Friday. That's CBS's Elizabeth Palmer reporting from Tehran.
