Mueller in recent months has interviewed multiple people linked to Stone, a former Trump campaign adviser. Some of those people have also testified before the grand jury.
"I am highly confident Mr. Manafort is aware of no wrong doing on my part during the 2016 campaign, or at any other time, and therefore there is no wrongdoing to know about,” Stone told ABC News. “Narratives to the contrary by some in the media are false and defamatory."
Manafort and his lawyers have visited Mueller's office at least nine times in the last four weeks, CNN reported on Wednesday.

Stone at the time made public comments that indicated he had been in touch with WikiLeaks founder Julian Assange about the release of Clinton's emails.
Stone in August released a video denying that he had advance knowledge of the emails.
At the time, he sent out out an email to his supporters claiming Mueller was poised to indict him as part of the ongoing investigation into ties between the Trump campaign and Russia.
Stone on Wednesday told ABC News that it is "not outside the realm of possibility ... that [Mueller] may consider bringing some offense against me.”
