NFTs would be the digital assets available for trade. In the test marketplace, it was mostly the standard “unique” pictures, but that was just for testing. The idea was to use NFTs as a proof-of-ownership of a digital asset. Instead of a picture of a monkey or something, they’d be like activation codes or in-game assets (skins, guns, etc) with the goal of creating a secondary market for digital assets. There was also the potential to use them for smart contracts, so that the original creator could get a percentage every time one of their assets was sold on the secondary market.

As for the Trump thumping, the only thing I saw was that tweet that said “TRUMP” a bunch, and considering the timing the consensus seemed to be that he was trying to exploit the algorithm. I haven’t seen him actively endorse Trump, though admittedly I haven’t been following very closely the last couple of years. It would be somewhat out of character for him though, he has been consistently vocal against Wall Street shenanigans, particularly predatory shorting and market manipulation.
