COOPER: New reporting tonight from CNN's Andrew Kaczynski shows long time Trump supporter Roger Stone appeared on an internet radio show on the same day that "The Wall Street Journal" says Stone sent an e-mail claiming he'd had dinner with WikiLeaks Founder Julian Assange. Andrew Kaczynski joins me now. So what did you and your team discovered about, about this time line and explain just the significance of it?</s>ANDREW KACZYNSKI, CNN SENIOR EDITOR, KFILE: OK. So this is Roger Stone on the Alex Jones show. He was on there on August 4th of 2016. Now it's significant because this is the same day on which he sent that e-mail claiming in which he had dined with Julian Assange. Now, what's equally very interesting about it is in the appearance, Stone said that devastating WikiLeaks were going to be coming out on Hillary Clinton, and he also claimed that he had spoken to Donald Trump basically that same day. So he would have spoken to Trump the same day or night in which he claim having dinner with Assange. So having those two things connected is very -- raises a lot of questions about his relationship with WikiLeaks.</s>COOPER: Has Roger Stone responded to CNN about your findings?</s>KACZYNSKI: So I e-mailed with Mr. Stone a little bit. He says that he was traveling from L.A. to Miami on the date in question. He actually says that in the interview with Alex Jones as well. So he claims he couldn't have dined with Assange, and he basically is saying it's, you know, a fake story and whatnot.</s>COOPER: All right. Andrew Kaczynski, I appreciate it. Thanks very much. Coming up, remembering Martin Luther King Jr. 50 years to the day since he was assassinated in Memphis. I'll speak with Dr. Cornell West about Dr. King's legacy.
