Facebook has been in a tailspin since Christopher Wylie blew the whistle on Cambridge Analytica's use of user data, and on Tuesday, he made a massive allegation across the pond. During his lengthy testimony before a British House of Commons committee, the 28-year-old former Cambridge Analytica employee suggested the user information gleaned from Facebook also helped swing the Brexit vote. He said Canadian political consultant AggregateIQ (AIQ) both worked on the official pro-Brexit "Vote Leave" campaign and had access to the data; he "absolutely" believes the data was used by AIQ, reports the AP. In its report, the New York Times describes Wylie colorfully: as a "a cerebral skate-rat" and a "pink-haired, nose-ringed oracle sent from the future to explain data."
