But I retain a suspicion that Huma could have been operating, er, ah, independently. Hillary wouldn't necessarily have known it...or, if she did, she wouldn't necessarily have had an objection.
Huma was operating at least in part through Clinton’s private email server, so Clinton must have known about it.
Huma herself has no independent influence or prominence other than as Clinton’s assistant. (Marrying Weiner came much later and he’s a relative nobody.)
There really isn’t much if any evidence to support Huma being an independent actor. Her role, job description, and pretty much entire life is as Clinton’s personal assistant.
