Deep background ????
What is that? Like Deep Throat and watergate?
FWIW, I looked up the definition of that and this is what it said.
"Deep background": This term is used in the U.S., though not consistently. Most journalists would understand "deep background" to mean that the information may not be included in the article but is used by the journalist to enhance his or her view of the subject matter, or to act as a guide to other leads or sources. Most deep background information is confirmed elsewhere before being reported.
Sounds like someone is spoon feeding a lot of propaganda to me. And if they truly did divulge "confidential/secret" information to anyone that does not have clearance to know about it, then they broke the law in doing so.
That only leaves me to believe that they are in fact trying to cover things up to suit themselves and write it the way they want it to read.
