Secretary of State Marco Rubio on Iran:
I wouldn't say we are on the verge of a breakthrough.
President Trump will always prefer to solve any problem diplomatically. Sometimes this is not possible.
But if there is a chance to do it, we will look into it.
Right now, it hasn't been very productive, because the Iranian demands are simply not only unacceptable but, in some cases, outrageous and ridiculous and downright unrealistic.
