Good catch -- thanks for posting. When she later stumped for him (at his request, I've read somewhere, though don't know for sure whether he did ask or if she suggested it) it would appear that she either didn't hold him responsible for turning the mic off after only 5 minutes, OR didn't hold a grudge, OR held the interests of the country above her own (seems to me justified) grudge.
Thanks for all the links you provide, Diogen. Always appreciated here.
