They have reportedly asked witnesses about Stone’s connections to WikiLeaks, and if he’s met the site’s founder, Julian Assange.
Stone told NBC in a statement that he has not been interviewed by the special counsel and “never discussed WikiLeaks, Assange or the Hillary disclosures with candidate Trump, before during or after the election.”
The lines of questioning come as Mueller probes Moscow's meddling in the 2016 presidential election, including ties between Trump campaign associates and Russia.
In March 2016, Russians successfully hacked Clinton campaign chairman John Podesta’s email account. WikiLeaks later released stolen emails from the DNC as well as emails from Podesta himself in the months leading up to the 2016 election.
Seizing on the controversy, Trump declared “I love WikiLeaks” at a campaign rally while he read some of the leaked messages.
According to NBC, investigators are also interested in Trump’s comments on the campaign trail about emails then-opponent Clinton deleted from the private email server she used while secretary of State
"Russia, if you're listening, I hope you're able to find the 30,000 emails that are missing," Trump said during the July 2016 press conference.
The White House later said Trump was joking when he made those comments.
Trump has repeatedly declared the federal Russia probe a “witch hunt” and has denied any collusion between his campaign and Russia.
