He deleted it after Trump said Nikky jam "was hot" and didn't even realize he was a guy.
I absolutely wouldn't be surprised if he learnt his lesson now that Trump doesn't even care to know his supporters. He might even hopefully vote for Kamala.
It's also possible that some of Trump's endorsements are paid for (let's be honest, people like kid Rock and hulk Hogan need all the publicity they can get these days)
I would still say all of this is a problem and certifies him as a jackass tbh.
Deleting the post after he felt personally offended doesn’t magically absolve him of having made the endorsement in the first place. And if he was paid for it that’s even worse imo.
