I admit I got all the way to the end waiting for the swastika, and figured, "eh, well it must be that thing."
Thing is, while I find this entirely plausible, unless there's an archive.org of the tweet before deletion, I don't think we can credibly tie this back to anything DeSantis wanted or approved.
He's in my top 5 list of people actively trying to destroy the US, but unless the provenance of the linked video can be proven I don't see this going anywhere. Folks who hate him aren't surprised, folks who don't will ask for more proof, DeSantis will deny if he acknowledges it at all.
