Roger Stone’s emissary with WikiLeaks founder Julian Assange has been identified, according to a report Wednesday evening.

New York radio host Randy Credico acted as the intermediary Stone has referenced in the past, sources told CNN.

Stone reportedly did not reveal the intermediary’s identity to the House Intelligence Committee when he made a closed-door appearance before the committee earlier this year, but then did disclose Credico's identity later, in private.

The House Intelligence Committee subpoenaed Credico this week. Martin Stolar, Credico’s attorney verified that Credico will comply with the subpoena and will testify on Dec. 15.

Credico has both Assange and Stone on his radio program as guests and met Assange in person this year. Credico did not confirm whether he would answer the committee’s questions and noted his First Amendment protections as a member of the press.

"I'm going to have to appear before them," he said, according to CNN. "I'm not sure I'm going to talk to them."

Stone testified before the House intelligence panel during a closed session in September and afterward he told reporters afterward he answered all questions, except he did not disclose the name of his intermediary with Assange. He did however privately reveal the identity to the committee later.

At the time, Stone claimed the exchange with his intermediary was an off-the-record discussion with a journalist and he would not disclose the journalist's identity, although he said he would follow up and ask the journalist if he could unveil the journalist's identity.

"I'm not going to burn somebody I spoke to off the record," Stone said to reporters after the hearing. "If he releases me, if he allows me to release it, I would be happy to give it to the committee. I'm actually going to try to do that."

Stone has said he had no direct contact with Assange and said he learned WikiLeaks had obtained Democratic National Committee emails in June via Twitter. He said he contacted the journalist, now known to be Credico, to verify the report was true.

Stone attracted scrutiny after he appeared to anticipate document dumps WikiLeaks during the 2016 campaign, saying, at one point, Clinton campaign chairman John Podesta's "time in the barrel" would occur soon. Stone has dismissed claims he had any prior intelligence that WikiLeaks would release Podesta's emails. Rather, he said the statement was based on his own investigations of Podesta.
