Here is another interpretation of events…

At 21:11:33, Georgie has binder in right hand. Loose papers have a white TAB on them… PIC 1
At 21:12:02 Trump looks at Georgie. George gives subtle nod YES and mouths it. The drop is on.
At 21:14:33 Georgie has switched the documents into his left hand so the drop is obscured by the passing coffin.
At 21:14:45 Bald agent behind him squares his body so his arm reach can get to documents with minimal lean.
At 21:14:47 A fresh program is passed by someone to left of agent, which he presumably takes.
At 21:14:49 The agent makes a subtle lean toward Georgie, and presumably swaps his program for the one with the white TAB.
At 21:14:51 Georgie has a very subtle head nod confirming he got it. (Not a good poker player, IMHO)
At 21:15:03 Georgie's program has no white TAB on it anymore.
Bush provided some dirt to Trump and co…. Cooperating.
At 21:15:04 Jeb knows it happened…and is looking at the agent in incredulity.
I haven't watched the whole video….but did someone else provide that white tabbed sheet to him earlier?
