At 4 p.m., advisors told Hashemi Rafsanjani that if he was not going to register as a candidate, he should write a message to the people and let them know. The former President agreed to draft a satement; however, an hour later, the advisors told others, "Hurry up. Rafsanjani is setting off to the Interior Ministry to register."
What had changed?
Rafsanjani had consulted the Supreme Leader's office. He had received a "not negative" response --- not a definitive green light to run but also not a rejection.
