Choice quote:
"There are other dramatic documents in Wylie’s stash, including a pitch made by Cambridge Analytica to Lukoil, Russia’s second biggest oil producer. In an email dated 17 July 2014, about the US presidential primaries, Nix wrote to Wylie: “We have been asked to write a memo to Lukoil (the Russian oil and gas company) to explain to them how our services are going to apply to the petroleum business. Nix said that “they understand behavioural microtargeting in the context of elections” but that they were “failing to make the connection between voters and their consumers”. The work, he said, would be “shared with the CEO of the business”, a former Soviet oil minister and associate of Putin, Vagit Alekperov.
“It didn’t make any sense to me,” says Wylie. “I didn’t understand either the email or the pitch presentation we did. Why would a Russian oil company want to target information on American voters?”"
