### Russian and WikiLeaks contacts
Wylie said that from spring 2014 through 2015 Cambridge Analytica representatives met representatives of Lukoil, that Nix's presentations included discussion of rumor and disinformation campaigns, and that in May 2018 he told the [[Senate Judiciary Committee]] that Lukoil "has formal information sharing agreements with the Russian Federal Security Service."[^30] Kaiser told the committee the discussions concerned a customer loyalty application for Lukoil's stations in Turkey, said she was told the data could also be useful for political activities there, and furnished a February 2015 presentation prepared by SCL Commercial; neither she nor Wylie believed that a contract resulted, and the committee stated that it did not independently corroborate the allegation that Lukoil intended to use the company to affect elections.[^30] The committee noted that the [[Office of Foreign Assets Control]] had added Lukoil to its Sectoral Sanctions Identifications List on September 12, 2014.[^30]

Wylie also told the committee that in spring 2014 Bannon approved focus groups about [[Vladimir Putin]] and Russian expansionism preparatory to a predictive model, and that Bannon and [[Konstantin Kilimnik]] were two of three people likely responsible for the idea.[^31] [[Sam Patten]], a consultant who worked for the company in Nigeria, Mexico, Kosovo and the Czech Republic, told the committee there was "no connection" between Kilimnik and Cambridge Analytica; Kaiser said that on the Nigerian project the company may have assisted its client in retaining former Israeli intelligence officers working privately to conduct opposition research.[^31]

The committee reported open-source accounts that during the 2016 campaign Nix emailed [[Julian Assange]] about the possible release of [[Hillary Clinton]]'s deleted emails, and that Assange said in October 2017 that [[WikiLeaks]] had rejected an approach by Cambridge Analytica. The committee obtained no additional information, and Bannon and others close to the campaign said they had no prior awareness of the contact.[^32] The committee also recorded that it was unable to obtain the company's corporate communications, which were in the hands of United Kingdom authorities, and that Nix "generally disregarded the Committee's requests for an appearance."[^33] It found "no convincing evidence that Russia's government or intelligence services worked with or through" Cambridge Analytica, Psy Group or Colt Ventures in furtherance of the 2016 interference.[^33] Cambridge Analytica, LLC is named among the respondents in matters under review 7207, 7268, 7274 and 7623 before the Federal Election Commission, in which Commissioners Shana Broussard and Ellen Weintraub issued a statement of reasons citing Volume 5 after a certification dated April 22, 2021; the text of the statement concerns the Russian Federation, the Internet Research Agency and the Trump committee and does not mention Cambridge Analytica outside the caption.[^34]

### Regulatory and criminal proceedings in the United Kingdom
The Information Commissioner's Office issued a monetary penalty notice of £500,000 to Facebook on October 25, 2018, the highest fine permitted under the Data Protection Act 1998, citing lack of transparency and security failures relating to the harvesting of data.[^35] The office also executed a warrant at the company's premises at 8 p.m. on March 23, 2018, seized servers and other material, and reported that Cambridge Analytica and SCL Elections entered administration on May 3, 2018, that an enforcement notice of May 4, 2018 required it to answer a subject access request from the American academic [[David Carroll]] that had been made in January 2017, and that the deadline of June 3, 2018 passed without compliance.[^18] The office reported that Nix and Kogan had declined invitations to voluntary interviews under caution and that it would have issued a substantial fine had the company not been in administration.[^18] SCL Elections pleaded guilty at [[Hendon Magistrates' Court]] on January 9, 2019, the day set for trial, to failing to comply with the enforcement notice; press reports gave the penalty as a fine of £15,000 with £6,000 in costs and a victim surcharge of £170.[^36] The Information Commissioner's 2020 letter to Parliament gives the fine as £18,000.[^37]

On October 2, 2020 the Information Commissioner, [[Elizabeth Denham]], wrote to the chair of the Digital, Culture, Media and Sport Committee that the office had concluded its investigation, that the company had purchased commercially available data amounting at one estimate to more than 130 billion data points, mostly about United States voters, to combine with Facebook-derived data from Kogan, that its models were mostly built from "off the shelf" tools, that the office found no further evidence to change its view that the company was not involved in the European Union referendum campaign beyond early inquiries about UK Independence Party data, and that it found no additional evidence of Russian involvement in the servers it obtained.[^37] The letter also reported evidence that in its last stages the company was drawing up plans to move its data offshore to avoid regulatory scrutiny, which it did not carry out before it ceased trading.[^37]

The Insolvency Service announced in September 2020 that Nix had given an undertaking disqualifying him from acting as a company director for seven years from October 5, 2020, having, in the service's words, caused or permitted SCL Elections or associated companies to act with a lack of commercial probity by marketing services including "bribery or honey trap stings, voter disengagement campaigns, obtaining information to discredit political opponents and spreading information anonymously in political campaigns." The service did not say whether any such services were performed, and Nix told Reuters he had made no admission of wrongdoing.[^38] The Digital, Culture, Media and Sport Committee had recorded in February 2019 that the Insolvency Service was investigating the directors of SCL Elections, SCL Group, SCL Analytics, SCL Commercial, SCL Social and Cambridge Analytica (UK) under the [[Company Directors Disqualification Act 1986]].[^39]
