Search all posts on this site for AF2. On or around New Year's, a planespotter had vp's plane af2 going someplace prison-like and returning with different call signs indicating no VP on board. That thread had discussion of it, a few links, and I bought into it. But obviously if it's true, it's not widely acknowledged or easily proven. So maybe false, maybe true. Hope that helps you get you started. The fact that the coin he received was obviously displayed instead of being accepted surreptitiously plays into this line of thinking as well.
