Immediately following today’s historic nuclear deal between the U.S. and Iran, Morning Joe’s Mike Barnicle shares his observations on Secretary of State John Kerry’s efforts to reach the agreement. “[Secretary Kerry] has worked tirelessly here and around the Middle East… and I’m sure what’s going through his mind this morning is: ‘How can you jump into the opposition so firmly, so strongly, right now when you don’t even know the details yet?’ It’ll be a real educational process that President Barack Obama and the Republicans and Democrats in the U.S. Senate will engage in,” says Mike in response to early criticism of the deal.
