Mueller has obtained audio recordings that may blow up Roger Stone's story about his contacts with Assange

Special counsel Robert Mueller has obtained audio recordings of radio interviews that Trump ally Roger Stone conducted with talk show host Randy Credico that could blow up Stone's story about how he came into contact with WikiLeaks founder Julian Assange.

CNN reports that the recordings shed doubt on Stone's claim that Credico served as his official back channel to Assange during the 2016 presidential election -- a charge that Credico has repeatedly denied.

Of particular interest is an August 23rd interview in which Credico asked Stone about his contacts with Assange, and Stone said that he communicated with Assange through "a mutual friend, somebody we both trust and therefore I am a recipient of pretty good information."

Given that Stone has claimed that Credico himself was that "mutual friend" who put him in touch with Assange, it wouldn't make much sense for Credico himself to question Stone about it on his own radio show.

In a March 2017 interview, Credico once again asked Stone about his "back channel" to WikiLeaks, despite the fact that Stone would later claim that Credico was the back channel.

"I described it as a back channel," Stone told him. "I think in another interview I may have said intermediary. In the third interview I said a mutual friend. They are all true. They're all consistent and what I learned from this person, and don't blame me if I had better sources than the mainstream media was very simply this, that Assange had a substantial of information on Hillary Clinton and he would drop it in October."

CNN reached out to Stone for comment on the new recordings -- but, according to the network, he "did not respond to repeated emails seeking comments and hung up when called by CNN's KFile team."
