Cambridge Analytica used data from Facebook and Politico to help Trump

Cambridge Analytica used its own database and voter information collected from Facebook and news publishers in its effort to help elect Donald Trump, despite a claim by a top campaign official who has downplayed the company’s role in the election. The data analysis company, which uses a massive database of consumer and demographic information to profile and target voters, has come under the scrutiny of congressional investigators who are examining the Trump campaign.

This week, the group became the focus of a new controversy after the Daily Beast reported that the company’s chief executive, Alexander Nix, had contacted Julian Assange in 2016. Nix allegedly asked the WikiLeaks founder whether he could assist in releasing thousands of e-mails that had gone missing on a private server that had been used by Hillary Clinton. Assange confirmed the contact but said the offer was rejected. The news prompted a top former campaign official, Michael Glassner, who was executive director of the Trump election campaign, to minimise the role Cambridge Analytica played in electing Trump, despite the fact that it paid Cambridge Analytica millions of dollars in fees. In a statement on Oct 25, Glassner said that the Trump campaign relied on voter data owned by the Republican National Committee to help elect the president. “Any claims that voter data from any other source played a key role in the victory are false,” he said. But that claim is contradicted by a detailed description of the company’s role in the 2016 election given in May by a senior Cambridge Analytica executive.
