On Capitol Hill, Cambridge Analytica whistleblower Chris Wylie told the Senate Judiciary Committee Wednesday that the voter-profiling company sought to suppress turnout among African-American voters and preyed on racial biases. Wylie testified that Cambridge Analytica harvested the data of up to 87 million Facebook users, without their permission, and used the data to “fight a culture war.” Cambridge Analytica was founded by billionaire Robert Mercer. Trump’s former adviser Steve Bannon of Breitbart News was one of the company’s key strategists. Wylie said he left the company due to efforts to disengage voters and target African Americans.

Chris Wylie: “Cambridge Analytica sought to identify mental vulnerabilities in voters and worked to exploit them by targeting information designed to activate some of the worst characteristics in people, such as neuroticism, paranoia and racial biases. To be clear, the work of Cambridge Analytica is not equivalent to traditional marketing. Cambridge Analytica specialized in disinformation, spreading rumors, kompromat and propaganda.”
