Facebook said late Friday that it had suspended Strategic Communication Laboratories (SCL), along with its political data analytics firm, Cambridge Analytica, for violating its policies around data collection and retention. The companies, which ran data operations for Donald Trump’s 2016 presidential election campaign, are widely credited with helping Trump more effectively target voters on Facebook than his rival, Hillary Clinton. While the exact nature of their role remains somewhat mysterious, Facebook’s disclosure suggests that the company improperly obtained user data that could have given it an unfair advantage in reaching voters.

Facebook said it cannot determine whether or how the data in question could have been used in conjunction with election ad campaigns. Cambridge Analytica did not immediately respond to a request for comment.
