Need to be able to explain it thoroughly though. We can't just grab onto every thought that passes by. I'm leaning towards him not being in DC as well but there are lots of ways they can accomplish that here in the US. We don't need to send the whole gang to China.

Occam's razor again. The real WH office is all ready to go and a set would have to be found/constructed/fiddled with. There are other people with him, each of them has to be explained, arranged, made to keep quiet. No leaks from them. That said, there have been a lot of discrepancies pointed out and even if half are illusions it's still a lot. Maybe a different approach would be fruitful. For instance, what point would it serve, and who would gain, if Biden and all the interactions in the Oval Office are staged? What if it is a setup in the real OO to make it look like a set? How can we even vet these videos of him?

edit: last sentence I mean, could they have shopped in cars seen in windows, the red building, stuck a black tape in the corner to look like a crack, etc.? I am presuming if that was a ploy there would be the best video editors, not the usual level of guys making memes.
