That’s horrifyingly true, but what time did he depart for Las Vegas? IIRC, the very next day, to fund raise and party with celebrities!
IIRC it was in the morning, which is why he had to go to bed early the night before. There is NO way he was being briefed by anyone during the night! He just toddled off to bed without a care while Americans were being slaughtered...but, what difference does it make?
