Hmmm… I'm not sure about Brennan and Clapper. Comey, maybe, but there are other things about Comey that indicate he isn't a bad guy altogether (he's a boob, for sure).
It may be that Zero really did pardon himself and Cankles, and left several underlings off the list and they now realize what he did. He fucked 'em all except the one(s) that have all the goods (HRC, Huma, etc.).
Theories, of course, but worth positing. Discussion helps.
