That is, if he allows justice to proceed accordingly. The threat to him is whether he would like to enjoy a peaceful post-presidential career, complete with well compensated speaking fees, or have the intelligence community go full medieval on his ass.
Given the choice, the decision should be quite clear - the key then is for BHO to cover his (political) tracks. That's why LL met with Bill: LL gets to recuse, handing the referral off to a career functionary, therefore processing it like a normal citizen ie convene GJ. Bill gets to skate or reduced penalty for playing the part of forcing the meeting and subsequent recusal.
Hillary has outlived her usefulness - her wanton treason was a result of assuming the power of the uni-party/NWO would continue unabated. Trump, Brexit, Putin, et al have a put a lie to that assumption. These people & events are the true black swans of this era.
Events are changing. Hillary is a just an expendable casualty of this re-ordering of world affairs.
If BHO is complicit in criminal wrongdoing or treason, then he HAS to go down first, so that he is stripped of his Presidential pardon powers. If he remains standing to issue pardons to the Clintons and any other targets of the FBI investigation, then he has built a wall around himself.
BHO has to fall first, then the others have no place to hide.
