Akiko Fujita (AF): Welcome back to Squawk Box. We are back for day three of Credit Suisse's Asian Investment Conference. We've been talking a lot about the business environment and trade. We're going to continue that conversation, maybe add a little politics into the mix, because our next guest is Reince Priebus, he's the former White House Chief of Staff under the Trump administration from January to July 2017. He previously served as Chairman of the Republican National Committee and he joins me here in Hong Kong. Glad to see you in Asia.

Reince Priebus: Hey I'm happy to be here, thank you for having me.

AF: There's certainly a lot to discuss but I want to start with some of the headlines that have been dominating at least the markets and we're talking about the Facebook story that broke several days ago. Cambridge Analytica coming out and saying they were able to harvest 50 million users' data to sway the election. Now the claim coming from Cambridge Analytica has been that this data that they got from Facebook had a significant impact on the presidential election. What's your read?

Reince Priebus: Well you know, I don't know how true some of these claims are. I mean certainly from the Republican National Committee's standpoint, which was the data firm of the Trump campaign, which is what we built at the RNC, we didn't use Cambridge. So I don't, I don't know, how true any of these claims are. I don't know if their folks were bragging that they were doing things that they weren't, maybe they were doing those things, I don't know.

AF: This was a firm though that was hired on by the campaign had very close ties, Robert Mercer, Steve Bannon.

Reince Priebus: That's what they say. But you know at the time, we just weren't relying on them so maybe initially they played ball with the campaign, but it wasn't soon after we merged with the Trump campaign, that they went on a full blown RNC data. So I think they themselves in November or December of last year said the same thing, that they were using RNC data not Cambridge's Analytica.

So look I don't know. I mean this is something that I think people are going to figure out pretty quickly. When you have losses like that in the markets, believe me, shareholders will make their claims and they will figure it out. So I'm anxious to hear what the story is, but as far as we're concerned, you know RNC data was the driver, we built something very special. Nothing's like our data. It's the best there is and that's what got President Trump at least on that piece of the campaign to where he was, not the company in the United Kingdom.
