Former U.S. President Donald Trump faces a new legal challenge - this time from the government he used to lead - with charges for illegally retaining classified documents and other crimes expected to be filed next week in federal court in Miami.

"This country is a mess. The way it’s going right now it’s not going to survive," Trump said.

With Sanctioning Zarif, chance was lost for exploring whether the JCPOA could lead to serious negotiations on other matters of concern to outsiders.

Foreign Minister Mohammad Javad Zarif on Friday reiterated that the US excessive demands will get nowhere, saying that President Donald Trump's recent claim over zero enrichment is repeating the US predecessor's mistake which caused Iran to ramp up nuclear enrichment.
