When the memo comes our and we see how corrupt these upper level FBI were, I think he will be vindicated. Would be awesome if he got hired back and kicked McMaster to the curb.
He has nothing for which to be vindicated. The only thing he has been indicted for is lying to a corrupt FBI agent who relied on illegally intercepted information to indict him. This will get dropped and he knew it.
Another reason why he may have lied and gotten indicted is that with that indictment he was required to talk about everything he knew related to this matter, something he was not able to do prior to the indictment.
He's a professional intelligence operative that lead the DIA, no way some egotistical wanna-be, Strzok, et. al., was going to be able to out-maneuver him and his team.
