SCIUTTO: "That's right. They say based on what they know, this is not out of bounds from their experience. Let me give you the reasons why. One to be clear, unmasking is not leaking. When a U.S. person's identity is unmasked at the request of senior national security official, it is not put out or tweeted out. That information is shared among those people with clearances. I am told that the NSA has to give approval to do that. The nasa security could not request. It is the NSA is making the decision."
