Ha! Even The Donald knows he blew it!
From Crooks & Liars:
There is no audio, only video of Donald Trump leaving the venue. But watch Melania and Ivanka in particular as he interacts with Jared Kushner about something, and starts pointing fingers and getting agitated.
Something did not please The Donald. Or else he was just coming down of his adrenaline high from that trainwreck of a debate.
