Speculation on why HRC did not want her revoked clearance publicized:
She's been selling secrets. We know this.
Perhaps she has been selling "secrets" even after her clearance was revoked?
Perhaps the people she's been selling "secrets" to will now wonder if the "secrets" are real since her access was revoked?
Perhaps now she is in a bigger pickle than before?
Buyers wanting a refund?
Payment already made?
Fake secrets for big $$$?
