I'm going to be wildly speculative here. Let's assume that the timing of this release helps the Trump administration and smears the US intelligence apparatus writ large. There's only one person on his team who has displayed the forethought, intelligence, and capability necessary to do something like this. Jeff Sessions obviously isn't. Bannon, while an effective and shrewd minister of propaganda not this sophisticated.
There is, however, one person who thinks twelve moves ahead like a chess grandmaster. I wonder what, if any, Peter Thiel's role is in all of this
