Not very credible - too many anonymous sources to believe everything written. This is likely a summary of what he wanted to hear more than what actually is happening. And Gasparino isn’t credible enough to accept what he writes as authentic/truthful.
He appears to have read on the subject now. His prior writings exposed his ignorance. I still doubt he spoke to anyone in the government that has knowledge that’s not already public. I doubt there’s any rift between the Treasury and Calabria at this stage,
