Great to hear him say this. A few weeks back, he mentioned pizzagate in a very dismissive light, in regards to the 'fake news' meme. I'm guessing he heard from some trusted sources that this isn't a joke.

From The Savage Nation (starting around 16:10):

They want war. Do you understand that? Do you understand what I'm saying? When I say 'neocon', they're identical to the liberals in the sense that they want war with Russia. Whether they want a cold war or they want a shooting war they want war with Russia for their own reasons. It's a 'Neocon Ventriloquist Trick'. They can't let go.

Do you really want nuclear war with Russia? You idiots you. You stupid fools, you. Here's a man who won the Nobel Peace Prize the minute he became President because the Commies who run the UN and, uh... the Nobel Peace Prize Committee are one in the same. They're all the same. They go to the same, lets say uh.. I wanna say, I don't wanna say the same 'pizzarias in Brooklyn', but you get the drift. If you're into that story. Those in the UN, who are given to that type of thing, and those in the UN who are given to that type of thing probably go to the same pizzaria in Brooklyn.

Its an... its an 'in joke' that only the truly in-people understand what I'm saying. In other words The same sick perverts in the UN and the Peace Prize Committee, they're the same people! They want war with Russia. Why? These are the same people who pretend to be in the Peace Business, now they want war?
