“I guess the question is once he’s testified before Mr. Mueller’s special counsel investigation, how can he now say I won’t make the same testimony in public claiming executive privilege. I think it is sort of like virginity, kinda,” Chris Matthews said.

“Once you start talking about a matter in your jurisdiction and then you say, ‘oh, I’m not doing it anymore.’ You can’t do it once you’ve started talking. I understand that’s how executive privilege works. Once you have given it up, you can’t grab it back. How do you see it?”

Sen. Kamala Harris, looking rather awkward, replied: “I’m not going to go with you on that metaphor, Chris.”
