In his recent interview with CNN's Anderson Cooper, Republican presidential candidate Donald Trump sharply criticized the way the Obama administration has been negotiating the forthcoming nuclear deal with Iran.

‘We are making a terrible deal," Trump said last week. "We have the wrong people negotiating for us. The Persians are great negotiators.
