They are adapting to being hounded constantly by "investigators" from the republican party, and I am sure most any competent lawyer would tell them (hillary and huma) to not discuss any elements of the weiner investigation or the phony email stuff with each other until it is resolved, otherwise the conversations become fair game for questioning so that they can be hounded and potential charges of "lying"-- the republican stock and trade. They are just removing the potential for charges that they are traveling together so would have opportunity to "get their stories straight".
So far, it appears that Huma may be guilty of one extremely heinous crime... using email.
Man, the mouth-breathing republicans have to beat the email stuff (which hillary was exonerated, not charged, but apologized for) to death as that is all they have... to deflect from the 11,000 things trump has done, and his upcoming court cases (he has roughly 75 of them pending, but the two that, in a normal world, would be disqualifying: November 28, he will have to testify in the Trump University fraud case, and will appear over the little matter of having raped a 13-year old girl on December 16th, as the woman is ready to face him directly. But ooooooh, hillary used the wrong email address! Tres horrible!
