Six days before WikiLeaks began releasing Hillary Clinton campaign chairman John Podesta’s emails, Roger Stone had a text message conversation with a friend about WikiLeaks, according to copies of phone records obtained exclusively by NBC News.

“Big news Wednesday,” the Stone pal, radio host Randy Credico, wrote on Oct. 1, 2016, according to the text messages provided by Stone. “Now pretend u don’t know me.”

“U died 5 years ago,” Stone replied.

“Great,” Credico wrote back. “Hillary’s campaign will die this week.”

But the text messages provided by Stone to NBC News show that Credico appeared to be providing regular updates to Stone on WikiLeaks founder Julian Assange’s plans in the days before the hacked emails were released. In the texts, Credico told Stone he had insights into Assange's plans through a longtime friend, who was also Assange’s lawyer, according to the text messages.

Reached Wednesday, Credico downplayed the text exchanges. “There's absolutely nothing there that I had any knowledge of anything that Assange was going to do because I didn't,” he told NBC News.

Stone said the messages support the story he's been telling all along. “These text messages prove beyond dispute that Randy Credico was the source who told me of the significance of the material that Julian Assange told CNN he had and would publish in June 2016 and that Credico’s source was indeed a woman attorney who worked for WikiLeaks," Stone said. "If Randy said anything different to the grand jury, he perjured himself under oath.”
