STEVE DOOCY (CO-HOST): On the other side of Capitol Hill, two witnesses from Fusion GPS, the opposition research firm behind the fake Trump dossier that helped kick start the FBI's Russia probe, they took the Fifth a lot yesterday.

JOSHUA LEVY: No American should experience the indignity that occurred today. No American should be compelled to appear before acongressional committee just to invoke his constitutional privileges.

BRIAN KILMEADE (CO-HOST): Why not? Yeah.

DOOCY: That's the lawyer for GPS. 

KILMEADE: Alright, here to react -- nobody should be able to revoke -- Fox News senior judicial analyst Andrew Napolitano. Judge, what was that? 

ANDREW NAPOLITANO: That was the lawyer for the two GPS guys basically saying you can't drag somebody before Congress just because Congress is curious about their work. And I happen to agree with him. We all want to know the origins of this fake dossier. Did the FBI pay for it? There are reports out there that the FBI offered $50,000 for it. Was it done by Trump haters, and was it totally made up? Or is there some evidentiary basis for it? We all want to know the answers to that, but just because Congress wants to know the answers to something doesn't give them the right to drag the person before Congress and force them to answer their questions. If I were the lawyer, I would have given the same advice, invoke the Fifth. They don't have the right to ask you these questions. 

AINSLEY EARHARDT (CO-HOST): Is that normal for the FBI to pay for a dossier? 

NAPOLITANO: Absolutely not. This is the dossier that [former Director of the FBI] Jim Comey spoke to President-elect Trump about in Trump Tower alone after the others had left the room. And the question is did he tell him about this because he wanted him to know about it directly from the source, the FBI. Or did he tell him about it because he wanted it like J. Edgar Hoover-like, dangle something over the president-elect's head. We know how that ended up. 

DOOCY: Didn't - I think I read that John McCain apparently gave the copy of the dossier to James Comey at some point. But what’s interesting is it does look like -- clearly it was a political, dirty trick document. But what's interesting is a source close to the matter told Fox News that Democratic staffers in the hearing were aggressive and ran interference to protect Fusion GPS. So it looks like the closer they get to the truth, the worse for the Democrats. 

NAPOLITANO: As incredible and reprehensible as are the contents of the dossier, which I'm not going to repeat, the Democrats would love nothing more that if it were true or if people believed it were true because it's just horrific about what the alleged personal behavior of then Mr. Donald Trump, which he has clearly and convincingly denied.
