Meanwhile, Vance told CBS News that a deal would “absolutely” come before November’s critical midterm elections.

“Look, I think that the deal could happen in the next week, but the deal could also happen months from now,” Vance said.

It’s not the first time administration officials have vowed a deal is imminent. Late last month, Trump said the U.S. and Iran had a near-finalized deal in place, though few details of that purported agreement were released.

However, Trump has made clear a deal will not be signed unless Iran agrees to relinquish all nuclear capabilities.

As negotiations continue to stall, the U.S. joined New Zealand, Australia, Canada and European allies on Wednesday in a joint statement condemning attacks by the Islamic Republic of Iran against “Iranian dissidents, journalists and Jewish and Israeli communities.” The statement, released by the State Department, urged Iran to end such attacks.

“Attempts to kill, kidnap, harass, intimidate, or otherwise attack people on our soil, undermines national sovereignty and international norms,” the countries stated. “These actions must stop immediately. We commend the work of countries to counter these activities, and we are together resolved to undertake further measures to halt them.”
