Mueller’s grand jury questions Roger Stone’s social media adviser

A social media specialist who worked for Stone’s political action committee in 2016, Sullivan received two subpoenas from Mueller earlier this month: one summoning him to meet with the grand jury, and the second requesting documents and other electronic information, according to Knut Johnson, an attorney for Sullivan.

As they left the courthouse, Johnson told ABC News that his client was cooperating with the special counsel’s ongoing investigation.

“It would be inappropriate for Mr. Sullivan to make any comments on what has happened and what is happening,” Johnson told ABC News. “He’s going to fully comply with all legal requests made to him for information and he’s done nothing wrong.”

Johnson declined to comment when asked what investigators wanted from Sullivan, saying, “We can’t get into that.”

As he departed the courthouse, reporters sought comment from Sullivan but Johnson insisted on answering for his client, saying with a chuckle that he is “always going to follow his lawyers’ advice.”

A lawyer for Stone declined to comment on Sullivan’s grand jury appearance. In a recent interview with ABC News, Stone confirmed that he employed Sullivan “for a couple of months” during Trump’s presidential campaign.

Stone served as an adviser to Trump during the nascent days of the campaign but left before the end of 2015, but his social media activity during the run-up to the 2016 election has raised eyebrows for its seemingly prophetic message about hacked emails belonging to Hillary Clinton’s campaign chairman, John Podesta.

Just six weeks before WikiLeaks began publishing emails belonging to Podesta, Stone tweeted out cryptic messages on Twitter alluding to some sort of reveal related to the Clinton campaign and specifically Podesta.

The special counsel appears to have shown a growing interest in Stone as part of the wide-ranging investigation. A number of Stone’s associates – including Sam Nunberg, Michael Caputo, and Ted Malloch – have told ABC News that Stone featured prominently in questioning with Mueller’s team.

ABC News has also previously reported that the special counsel has issued a subpoena to John Kakanis, a former driver, accountant, and operative for Stone.

Stone says he has not been summoned to meet with the special counsel but told ABC News that if he ever does meet with Mueller’s team, he “will never betray this president.”
