A former director of Cambridge Analytica, who visited WikiLeaks founder Julian Assange after the 2016 US presidential election, was subpoenaed by special counsel Robert Mueller's office and cooperated, according to her lawyer.
Brittany Kaiser was a director at the controversial data company that worked for the Trump campaign and visited Assange in the Ecuadorian embassy in London where he has been living since he was granted asylum to avoid extradition in 2012.
Kaiser's lawyer Jim Walden told CNN, "The Mueller subpoena was issued long ago, and Brittany has already discharged her obligations. Whatever interest there was in Brittany seems past."
The news was first reported by The Observer newspaper in London.
The special counsel's office did not immediately respond to CNN's request for comment.
Last June, The Guardian reported that Kaiser had met Assange in February 2017, a few months after the 2016 election. After that report, Kaiser told CNN that she and Assange had not discussed the election.
Walden would not confirm Kasier had been cooperating with the special counsel's investigation when CNN contacted him last month, but said in a statement at the time, "Without commenting on any specific investigation, Brittany has been fully cooperative with the several pending investigations. I believe the investigators have found her to be credible, candid, and helpful. I do not believe she faces any legal jeopardy, as she did nothing wrong."
Cambridge Analytica has come under fire over allegations it misused the personal Facebook data of millions. Former Trump adviser Steve Bannon was one of the company's founders. The company has since shut down.
The company has likewise struggled with the fallout of undercover recordings by Channel 4 News in the UK that showed executives at the firm discussing Cambridge Analytica's efforts on behalf of the Trump campaign and the lengths to which they said they would be willing to go for prospective clients, including then-CEO Alexander Nix suggesting they would "send some girls around" in order to obtain compromising material on a hypothetical candidate.
Cambridge Analytica said in a statement in March it was suspending Nix and has denied it misused Facebook data for the Trump campaign.
According to her LinkedIn profile, Kaiser spent four years at the company and left in March of last year, around the time the scandal about the firm erupted.
