Cambridge Analytica has tweeted that it did not received Twitter data from GSR or Aleksandr Kogan.
Cambridge Analytica has never received Twitter data from GSR or
Aleksandr Kogan, and has never done any work with GSR on Twitter data. GSR was only ever a contractor to Cambridge Analytica and we understand it did work for many other companies.

Companies, developers and users have access to public data through Twitter’s application programming interfaces (APIs). The company sells the data to organizations, which often use them to analyze events, sentiment or customer service.
Enterprise customers can access the last 30 days of tweets or access tweets as far back as 2006. The customers have to explain how they plan to use the data and who the end users will be. Twitter doesn’t sell private direct messaging data.
Social media companies have come under intense scrutiny after data of 87 million Facebook users were leaked and questions were raised on the privacy of its users.
