Special Counsel Robert Mueller appears to be zeroing in on Roger Stone, a longtime ally of President Donald Trump who briefly served on Trump’s presidential campaign. So far, prosecutors have secured testimony from at least nine Stone associates, including some who were subpoenaed.
Mueller is investigating Russian interference in the 2016 campaign and potential collusion between Trump’s team and Russia. Stone vehemently denies participating in any conspiracy with the Russians and says the Mueller investigation is a sham designed to hurt Trump.
Here is a list of the Stone associates under scrutiny and their interactions with Mueller.
Former Trump campaign aide Michael Caputo was pressed for information about Stone during his voluntary interview with investigators in May, people familiar with the questioning told CNN. Caputo and Stone worked together on Republican campaigns before Trump’s bid in 2016.
Author and commentator Jerome Corsi, a well-known conspiracy theorist, met with investigators in September after receiving a subpoena. Corsi claimed his own research inspired Stone to predict trouble for Hillary Clinton’s campaign chairman John Podesta before WikiLeaks released Podesta’s emails.
Radio show host Randy Credico was subpoenaed in August and testified before Mueller’s grand jury. Stone claimed that Credico was his intermediary to WikiLeaks founder Julian Assange during the 2016 campaign. Credico denies this characterization but says he is friends with both men.
Kristin Davis, a friend of Stone’s who became known as the “Manhattan Madam” for running a high-end prostitution ring, testified before Mueller’s grand jury in August. She later told CNN that investigators had “concern for some things that (Stone) seemed to predict,” including WikiLeaks’ releases in 2016.
Mueller’s team subpoenaed political operative John Kakanis, who worked as Stone’s assistant and has insights into some of Stone’s business dealings, a source familiar with the situation told CNN. The subpoena was issued as investigators zeroed in on Stone’s finances and tax returns.
Author and former professor Ted Malloch was questioned by the FBI in March. He says he was asked about Stone, Corsi and WikiLeaks. Malloch was an informal adviser to Trump’s campaign. Like Stone, Malloch has claimed the Russia investigation is part of a secret plot to undermine Trump.
Political aide Andrew Miller voluntarily spoke with investigators in May. He was subpoenaed to testify at the grand jury, but he is fighting that subpoena in court. Stone’s super PAC paid $9,000 to Miller’s consulting business during the 2016 campaign, according to federal records.
Former Trump campaign aide Sam Nunberg testified before Mueller’s grand jury in March. Around that time, Nunberg said that investigators “want me to say that Roger was going around telling people he was colluding with Julian Assange.” Nunberg said he wouldn’t implicate Stone in collusion.
Social media adviser Jason Sullivan appeared before Mueller’s grand jury in June after receiving a subpoena for his testimony. He previously did social media work for Stone’s political action committee, which promoted Trump’s candidacy during the 2016 presidential campaign.
