The Wall Street Journal reports that Special Counsel Robert Mueller has requested Cambridge Analytica, the data firm that worked for President Trump's campaign, turn over the emails of all employees who were involved with the campaign.
The Journal says it was a voluntary request, as was another from the House Intelligence Committee, which the company went along with. The paper also reports Cambridge Analytica CEO Alexander Nix was interviewed by the House Intelligence Committee via video call this week as part of its investigation into Russian meddling in the 2016 presidential election.
In October, The Daily Beast reported that Nix sent an email to a third party that said he contacted WikiLeaks founder Julian Assange about how he could assist his website with releasing some of Hillary Clinton's deleted emails. Assange told The Daily Beast he was able to "confirm an approach by Cambridge Analytica and can confirm that it was rejected by WikiLeaks."
