What he failed to mention is that the tokens in Trump's wallet were airdropped to him, likely without Trump even realizing it. Several of Trump's crypto wallets are publicly known, and people send coins and NFTs to them all the time. Trump has no more endorsed Stone's "MAGA Memecoin" than he has the "HarryPotterTrumpHomerSimpson777Inu" tokens that also sit in his crypto wallet.
Elsewhere, Stone disclosed, "My promotion of MAGAMemecoin is, of course, sponsored." I haven't been able to find where he has disclosed the amount he was paid for these promotions, as he is required to do.
