The fun thing about Trump is that he's largely taken credit for the booming stock market, and really tied himself to it. Now that the market is melting down, so is Trump. He's trying to say that he shouldn't be blamed for the Corona virus, which is obviously true, but it wouldn't have been an issue if Trump hadn't made it an issue. He used the market as a metric for his success, while few others would. Now that the market is collapsing, that metric doesn't work so well for him and he's getting loud about it. You might say that it's a defective infective invective corrective.

Having gotten that out of the way, the issue I have with Trump on this has yet to materialize. He doesn't care about anything other than his success metrics, which are really just in his own mind, but they clearly weigh on him heavily. So, I feel that his past record suggests that he is very likely to respond poorly if there actually is a significant outbreak in the US. All he will care about is keeping it from being tied to him, not solving that, or anything else. Pence is an example of that. He's a weak sack, and Trump surely knows that. Putting him in charge is almost certainly a means of trying to control any message, as well as creating a scapegoat if one becomes necessary.
