She probably doesn’t “know” but she undoubtedly had her email set for IMAP so it could be accessed from multiple devices e.g. her phone, laptop, home PC etc.
Ignorance is no excuse, besides she might want to lawyer-up before she starts blabbing about what she knows and doesn’t know.
No ... my point isn't at all to excuse her.
I'm pointing out that possibly Weiner downloaded them without her knowing because, if true, it's an indication that they are going to be damning to the Clinton's. If Weiner did this behind Huma's back - yeah sure it's an example of why you don't put classified stuff on non secure email accounts ... because your dopey spouse may well know your passwords and a thousand other reasons ... but in this case I'm saying that if this was Weiner's insurance policy cache, created w/o Huma's knowledge (or maybe both of them created it - Huma may also have wanted insurance) ... that would suggest that they are very very very bad news for the Clinton's.
In other words, they aren't just there because Huma happened to use that machine for email ... but are specifically there, designed to be there, as a weapon if needed. Hence, probably potent.
