It's always been about 9/11 with Trump.
On the very day, he was interviewed by WWOR/UPN9 and said he couldn't believe planes could penetrate the steel.
"You had the steel on the outside of the building… that's why when I first looked and you had big heavy I-beams, when I first looked at it I couldn't believe it, because there was a hole in the steel… I said, 'How could a plane, even a plane, even a 767…'
"Steel frame" -"framed by Steele Dossier
Also, in a live television interview on 9/11, Trump drew upon his knowledge of skyscraper construction, stating that the World Trade Center towers were "rock solid" and that he believed the attackers must have used hidden bombs inside the buildings alongside the planes to bring them down.
In his 2000 book, The America We Deserve, published just a year before the attacks, Trump explicitly mentioned Osama bin Laden as a major threat to American security.
Remember the symbolism in his matress commercial?
How about his hat:
45 - 47
4+5 - 4+7
9 - 11
Has he always known the truth and does he hold the cards on those responsible?
Has he been leveraging that truth to move mountains?
Is today the day?
