The former head of Cambridge Analytica admitted on Wednesday his firm had received data from the researcher at the center of a scandal over Facebook users¡¯ personal details, contradicting previous testimony to lawmakers.

Cambridge Analytica, which was hired by Donald Trump in 2016, has denied its work on the U.S. president¡¯s successful election campaign made use of data allegedly improperly harvested from around 87 million Facebook users.

Former chief Alexander Nix, in earlier testimony to Parliament¡¯s media committee, also denied the political consultancy had ever been given data by Aleksandr Kogan, the researcher linked to the scandal.
