In a modern day conversation with Shaun, he tells us that he believes Washington aquired (or at least used) the Apple after Connor had finished his own battle with the Templars.

Don't know, I really don't understand the lack of the creed in ACIII, they didn't even have the 'Nothing is true, everything is permitted' line.

Either an Abstergo employee/Templar, an Assassin, or a member of Erudito. I suspect the last. But no-one really knows for sure, other than the writers at Ubisoft.
