Secretary of State Marco Rubio on Iran:
I wouldn't say we're on the verge of a breakthrough.
President Trump would always prefer to solve every problem diplomatically. Sometimes that's not possible.
But if there's a chance to do it, we will explore it.
Right now, it hasn't been very productive, because the Iranian demands are simply not just unacceptable but, in some cases, outrageous and ridiculous and really not realistic.
