Be careful with our assumptions. I wouldn't put it past a republican to have done it. Ideally I'm hoping for a RAT, but republican's have done this sort of thing before. It makes them feel special when they give info to a reporter. And they are dumb enough to leak it to CNN thinking they will get good coverage from them in the future for helping them out.
On a slightly different topic, did you know Fox News actually had this story first; however, they kept the actual message under wraps because they didn't want to help the enemy. So I guess we can all assume what this says about CNN.
You are correct...Carl Cameron reported this tonight...in fact I thought Carl said he himself was contacted...in that case Carl knows who the leaker is.
That means Fox News knows who the source of the leak is.
Makes you wonder, though. Would a Dem leak to Fox?
