On Thursday, Mr. Mueller subpoenaed the man Mr. Stone claims was his back channel to WikiLeaks throughout the campaign—New York comedian and radio personality Randy Credico. The subpoena was confirmed by Mr. Credico’s attorney, Martin Stolar.Separately, self-described “Manhattan Madam” Kristin Davis, who has close ties with Mr. Stone, testified Friday before the grand jury hearing.. The Wall Street Journal has reviewed emails showing Mr. Stone told Mr. Credico in September to “please ask Assange” for information that would be damaging to Democratic presidential nominee Hillary Clinton.
Mr. Credico has denied being a conduit between WikiLeaks and Mr. Stone. He says he didn’t have a relationship with Mr. Assange until the WikiLeaks founder agreed to do his radio program on Aug. 25, weeks after Mr. Stone claimed to be in touch with him.Mr. Stone has said WikiLeaks never gave him any information and that he never had special access to the website’s material.
Mr. Stone said Friday that while Mr. Credico told him in the summer of 2016 that WikiLeaks planned to release “substantial information on Hillary Clinton” that October, Mr. Credico didn’t tell him “what the source, content or scope of the WikiLeaks disclosures would be.”
.. Mr. Credico told the Journal on Thursday he was a “nervous wreck,” but he indicated that he plans to appear before the grand jury.
.. an aide to Mr. Stone, Andrew Miller, was held in contempt of court for refusing to testify before the grand jury. A judge had rejected Mr. Miller’s argument that Mr. Mueller’s appointment was unconstitutional and ordered him to answer questions. His lawyer, Paul Kamenar, said he asked to be held in contempt to appeal the judge’s ruling.
