In March 2018, multiple media outlets broke news of Cambridge Analytica's business practices. The New York Times and The Observer reported on the Facebook and Cambridge Analytica data breach, in which the company used for political purposes personal information acquired about Facebook users, by an external researcher who claimed to be collecting it for academic purposes. Shortly afterwards, Channel 4 News aired undercover investigative videos showing Nix boasting about using prostitutes, bribery sting operations, and honey traps to discredit politicians on whom it conducted opposition research, and saying that the company "ran all of (Donald Trump's) digital campaign". In response to the media reports, the Information Commissioner of the UK pursued a warrant to search the company's servers. Facebook banned Cambridge Analytica from advertising on its platform, saying that it had been deceived. On 23 March 2018, the British High Court granted the Information Commissioner's Office a warrant to search Cambridge Analytica's London offices.
