In defense of @sneakypete , I'd say his argument is that the loyalty obligation DeSantis had to Trump is inherent in Trump supporting him in 2018, and doesn't need to be explicitly stated to exist. I personally don't agree with that argument, but I think that's his point. Therefore, you don't need a link or direct quote.
It goes deeper than this. Trump's career saving support for RDS in both the 2018 primary and again in the general elections is only where it begins.
Beyond his using Trump to save his career, RDS was vocal and effusive in his praise of Donald Trump --- from the economy (not trade), to judges, to appointments, immigration, the military, Israel, his support and push for freedom in our hemisphere, his handling of COVID and assistance for Florida ---- RDS couldn't stop praising President Trump.
In speeches, interviews, tweets, going back to his impassioned soliloquy on the debate stage defending Trump against attacks from every corner of the political sphere the likes of which no President has endured, ending with the promise "I am not going to pile on" ----- RDS presented himself as a loyal supporter of the President.
Everything changed when DeSantis crossed the term limits Rubicon in Florida and jettisoned the President. In so doing, RDS proved himself to be a lying fraud and backstabbing little bitch ----- not only toward the President, but toward his supporters, as well.
On the plus side, RDS has become the author of one of the most stunning and ultimately fatal self-inflicted political wounds in American history.
