However, the analytics firm is also under scrutiny over campaigning for the 2016 referendum when Britons voted to leave the European Union.
Cambridge Analytica and the leaders of the Leave.EU group have previously boasted about working together during the Brexit campaign. However, they have since retracted their claims, saying no contract was signed and no work was completed.
Parliament is investigating the links between Cambridge Analytica and Leave.EU as part of an investigation into fake news.
Did Cambridge Analytica and Leave.EU work together?
Arron Banks, the co-founder of Leave.EU, said in a book that in October 2015 his group hired Cambridge Analytica, a company that uses “big data and advanced psychographics” to influence people. In a November 2015, Leave.EU said on its website that Cambridge Analytica “will be helping us map the British electorate and what they believe in, enabling us to better engage with voters”.
In the same month, Cambridge Analytica director Brittany Kaiser spoke at a Leave.EU news conference. She said her organization would be “running large-scale research of the nation to really understand why people are interested in staying in or out of the EU”.
In February 2016, Cambridge Analytica chief executive Alexander Nix wrote in Campaign magazine that his company was working for Leave.EU. “We have already helped supercharge Leave.EU’s social media campaign by ensuring the right messages are getting to the right voters online,” said Nix, who was suspended by the company this week.
Leave.EU’s communications director Andy Wigmore also said on Twitter last year that his campaign group had used the company. “You should use Cambridge Analytics,” he said, adding that he could “highly recommend them”.
