Cambridge Analytica, the shadowy data firm that helped elect Donald Trump, specializes in “psychographic” profiling, which it sells as a sophisticated way to digitally manipulate huge numbers of people on behalf of its clients. But apparently, when you’re trying to win a campaign, prostitutes, bribes and spies work pretty well too.

On Monday, Britain’s Channel 4 News ran an explosive exposé of the embattled company. Going undercover as a potential client, its reporter filmed Cambridge Analytica’s chief executive, Alexander Nix, talking about entrapping his clients’ opponents by sending “very beautiful” Ukranian sex workers to their homes. He spoke of offering bribes to candidates while secretly filming them and putting the footage online, of employing fake IDs and bogus websites. Mark Turnbull, the managing director of Cambridge Analytica Political Global, described how the company “put information into the bloodstream of the internet” and then watched it spread.

This story came two days after a joint investigation by The New York Times and The Observer of London reported that Cambridge Analytica harvested private information from over 50 million Facebook users without their permission. That, The Times wrote, “allowed the company to exploit the private social media activity of a huge swath of the American electorate, developing techniques that underpinned its work on President Trump’s campaign in 2016.”

After days of revelations, there’s still a lot we don’t know about Cambridge Analytica. But we’ve learned that an operation at the heart of Trump’s campaign was ethically nihilistic and quite possibly criminal in ways that even its harshest critics hadn’t suspected. That’s useful information. In weighing the credibility of various accusations made against the president, it’s good to know the depths to which the people around him are willing to sink.
