Vice President Vance's planned departure for Islamabad was delayed for hours Tuesday as Iran's leadership remained divided over whether to participate in a new round of peace talks, according to U.S. officials and sources with knowledge of the situation.
Why it matters: With the ceasefire expiring Tuesday night, every hour Vance spends in Washington is an hour closer to a resumption of hostilities. Iran has yet to decide whether it's coming to the table at all.
