Facebook Inc. is reviewing whether one of its own research employees knew about a leak of user information on 50 million people to Cambridge Analytica, the advertising data firm that helped Donald Trump win the 2016 presidential campaign.

Joseph Chancellor works at Facebook as a social psychology researcher and is under review, according to the company. Previously, he was co-director of Global Science Research, the company that obtained information on Facebook users and their friends through permissions they gave a personality quiz app. Chancellor didn’t respond to a message via LinkedIn seeking comment.
