What are you talking about?
Did you even look at the link I posted?
A private firm/private investigator generated the report and gave it to lots of people.
The news media could have printed it at any time. The unverified nature of the reports caused them to pause. BuzzFeed chose to stop sitting on it.
Trump has accused the US Intelligence employees of leaking the report. He keeps repeating that.
IT DID NOT HAPPEN, no one employed by the intelligence agency leaked anything.
And why did buzzfeed "stop sitting on it" specifically on Jan. 10?
Jan10, morning. Intelligence report includes a summary. Obama says "What does this have to do with anything?". They say "Just a heads up that it's out there, in case it gets in the media."
Jan 10, after briefing. At least 2 persons with direct knowledge tell CNN about the summary being included. This is called a "leak". This is NOT supposed to be public information.
Jan 10, 4pm. CNN runs story.
Jan 10, 6pm. Buzzfeed publishes all 35 pages - referencing the leak and the CNN story.
Also, it turns out that the dossier summary wasn't part of the official briefing documents. They showed Obama and Biden as an "aside". Trump was later given only a verbal heads up 1-on-1 with Comey. His official briefing did not have the 2-page summary.
----------------------------------
As an alternative view, it's also equally possible that the reason it was shared in the briefing at all that day was because buzzfeed had already decided to publish. In writing the story, they would have reached out to the agencies for any comment. Knowing it would hit the public any minute, they whipped up a summary as an FYI.
Either way, the leak to CNN is problematic. Although CNN states that the dossier is full of completely unverified allegations, nowhere do we get the impression that it was included as a "heads up". The mere (leaked) fact that a summary, written by US intelligence officials, was provided to the president gives it a level of seriousness that it does not deserve. It makes it seem as if officials are really investigating it.
Obama's reaction should tell you where to file this one: snug between the faked moon landings and Pizzagate.
