That proves squat. Still has nothing to do with the Lauer interview.
Sure it does. It was one of the few one on one media appearances she has made since the endorsement. She made it public fodder. A follow up is not out of the ordinary. We would expect the same if the child was Chelsea and the person was Hillary. Or if Al Gore has endoresed Hillary and one of his kids had an issue and it was blamed on Bush and PTSD.
