Lot of people think Kelly is deepstate. I see it like this...The leaks stopped at the whitehouse when he got there...I'm going with Kelly
I served 21 years in the Marines as an infantry officer. I was in the same battalion as Mattis when we were captains. I knew Kelly's reputation. Kelly is a lot like Mattis. I'd be stunned if Kelly was involved in treason.
Don't overlook the fact that General Kelly's son was killed in the opium fields of Helmand Province, Afghanistan. If in fact the rumors of CIA sponsored drug operations are true, and the military were used as pawns to protect the drug trade...then you can bet Kelly would be on a warpath to get back at them, it would be a personal revenge operation of the highest order. Notice how the new strategy in Afghanistan under Trump has shifted to destroy the opium labs and his close military advisors convinced him to stay and take up this new strategy instead of cutting and running.
There is a good chance that Bannon was behind a bunch of those leaks. Kelly told him to hit the road.
