I was wondering this myself a day or two ago, so went to wikileaks and did some searching (and posted about it too in a few threads... sorry, no links handy).
The bottom line is - there were about 5 emails that mentioned yoga. None of them were from Canky. I think two were just in the subject. All were just kind of happinstance, and not a focal point, reference to yoga in general. A couple may have been from or two Huma.
It's easy enough to search... and see them yourself.
I don’t need to see them. I’m an old lady, I lived through the Clinton presidential years; and I already know what she’s made of.
It’s not good material.
