'A treasure trove for the investigation': CNN panel details Mueller's focus on Roger Stone's WikiLeaks connection

CNN contributor Bianna Golodryga noted Monday that whether or not Trump ally Roger Stone actually met with WikiLeaks' Julian Assange during the 2016 campaign, the information obtained from his testimony before special counsel Robert Mueller's grand jury will be a boon for the investigation into Russian meddling.

Stone, Golodryga noted, "has been at the front of this relationship with WikiLeaks." She cited Twitter direct message screenshots acquired by The Atlantic in February of this year that countered Stone and Assanges' claim that they had never met or interacted. With the Wall Street Journal's reporting today that Mueller is probing a 2016 message the Trump confidante sent to campaign aide Sam Nunberg, the relationship has moved back into the spotlight.

"There's this recurring theme of had he spoken with Julian Assange, when did he speak with WikiLeaks," the contributor noted.

Stone, Golodryga noted, claimed the email he sent to Nunberg in August of 2016 was a "joke" he was playing on the controversial aide, though she doesn't understand "what's so funny."

"All of this is confusing," she said, but "at the same time offers a potentially huge treasure trove for the Mueller investigation."

CNN legal analyst Jeffrey Toobin noted that the Stone-Assange news is particularly interesting given that Mueller has not yet filed any charges regarding the Democratic National Committee's hacked emails, which WikiLeaks had a hand in.
