I am not reading anywhere the possibility that the Flynn transcripts were intercepted by the NSA and leaked to the press.
Check out Lou Dobbs show from last night with Judge Napolatano. The NYT article in January that got the whole Flynn thing going said they were given them. They should have never been recorded or at the very least transcribed when he was speaking.
