You mean where he lied? He makes everything about himself, despite the fact that he wasn't even there. Of course, the GOP is attacking Obama and Biden for hiding out on AF1 during the attack. Of course, it happened 7 years before Obama was in office but the GOP and it's followers are stupid, so....
And, Trump was nowhere near ground zero. When the towers went down he went on the radio to boast that he now had the tallest tower in NY. He wouldn't go anywhere near Ground Zero. Coward.
