President Trump tweeted about this interview with Judge Andrew Napolitano speaking to FNC's Martha MacCallum on Monday's edition of 'The Story.'



“He’s got a very good point. Somebody in the Justice Department has a treasure trove of evidence of Mrs. Clinton’s criminality at her own hands, or through others, that ought to be investigated. I fully agree with the President on that.” @judgenapolitano on @marthamaccallum Show — Donald J. Trump (@realDonaldTrump) February 27, 2018



MARTHA MACCALLUM, FOX NEWS: 'You know who' is [attorney general] Jeff Sessions.



ANDREW NAPOLITANO: The 'you know who' is probably Bob Mueller. Jeff Sessions would say, 'no it involves Russia, I can't comment now.'



MACCALUM: I think he's talking about the attorney general.



NAPOLITANO: Is Jeff Sessions the attorney general or?



MACCALLUM: Or [deputy attorney general] Rod Rosenstein.



NAPOLITANO: Somebody in the Justice Department has a treasure trove of evidence of Mrs. Clinton’s criminality at her own hands, or through others, that ought to be investigated. I fully agree with the President on that.

Napolitano was referring to a moment in Trump's interview Saturday night with FNC's Jeanine Pirro where the president says 'you know who' needs to look into the past crimes of the Clintons: TRUMP: Somebody should look into it. Because what they did is really fraudulent and somebody should be looking into that. And by somebody, I'm talking about you know who."
