He doesn’t have a real account. Neither of the ones on nostr was ever verified/announced by his campaign. And the methods I mentioned would be sufficient if they had.

he did have this statement in 2023 while talking about Jack and censorship.
"Figuring out how to make censorship proof, social media sites, and they’re doing that with Nostr. Some of this blockchain technology that’s coming out of Bitcoin will be very useful"
Not really verification of anything except that he was aware of nostr. Especially for a figure in a position such as him. Needs to be an explicit verification that it’s his account.
