If this really is Trump’s message, there are two things I don’t understand.
Why is he talking about the FBI following his orders? If he really managed to do that it would have been better not admitting to it publicly.
Why go against Desantis if he hasn’t said anything yet about being interested about the presidency?
Maybe he knows something about DeSantis that he isn't saying. But, DeSantis hasn't being going after him publicly so he shouldn't be attacking him publicly.
