Bill Priestap has been thought to be cooperating for some time, mostly because he was right in the eye of the storm and his name is never, never mentioned. Priestap was over Strozk, I believe, as a direct supervisor, right? McCabe was over all the investigators of Hillary.
** CTH has posted McCabe’s RESPONSE. **
A ready made diatribe of his awesomeness and that Trump is behind all of his troubles, because the FBI has been made politicized.
I believe LS has proposed that Priestap is singing like a bird.
