British investigators searched Cambridge Analytica's London offices amid intense scrutiny over whether or not the firm used illegally gathered Facebook data.
Cambridge Analytica has been connected to the Trump campaign. But now officials across the pond are raising questions about the firm's role in Brexit. A former employee told The Guardian the firm worked directly with the Leave.EU campaign and the pro-Brexit party UKIP.
More than a dozen members of the Information Commissioner's Office spent several hours searching and gathering evidence late Friday evening and into early Saturday morning after a judge granted a warrant Friday.
Both Facebook and Cambridge Analytica have denied any wrongdoing.
