Headline at The Washington Post. I'd make that a free-access link, but I only have 4 left to give this month and it's only the 18th. And it's one of these 31-day months, too, so I've got to be extra stingy.
I'll cherry-pick the lawprof talk:
“They have little options here in terms of protecting their interests,” said Jonathan Shaub, who teaches law at the University of Kentucky and has advised previous White Houses on the use of executive privilege. “Some have claimed the Fifth Amendment, even though I don’t think they actually think that they have committed any crimes. But given the language that has been used and the insinuations, I can understand why their counsel would say, ‘Just don’t say anything, because we don’t know what they’re willing to do and what they’re willing to prosecute.’”
You don't think they actually think that they have committed any crimes. But what do they need to believe? Is it enough that they believe that the current administration will do anything to get revenge on political adversaries? Professor Shaub can understand why their counsel would say they should plead the Fifth, but would he advise his clients to plead the Fifth based on the idea of not knowing what the Trump administration is willing to do?
