The professor’s *general* Fifth Amendment analysis is almost certainly correct, but applied to this very specific situation, which includes a pardon for past statements, I’ll give Fauci’s lawyers some deference that they’ve gone through the analysis and weighed the risk of perjury & contempt.

It certainly sounds like Fauci is saying that he thinks Paul is trying to trick him into perjuring himself. But that can't justify invoking the Fifth Amendment, otherwise anyone could get out of testifying anytime by claiming that, if they testified, they might lie. That can't be right.
