There was no actual work done, the place wasn't open to the public so there was no pressure. I highly doubt he did more than look at the actual workers show how stuff is done and then pose for photos that make it look like he's doing anything.
My point was that for it to be his idea he would've had to think about doing actual work. Even if he dismisses doing any work the thought would still have to cross his mind. I have a hard time believing it was his idea because doing actual work wouldn't even cross his mind.
He thinks of everything as a photo/soundbite-op. And since he’s a raging narcissist, he doesn’t think it can go wrong or look bad because he’s perfect in every way in his head.
