Cambridge Analytica whistle-blower to cooperate

The computer expert who alleges a trove of Facebook data was improperly used to help President Trump’s campaign said he will cooperate with a Justice Department investigation.

Christopher Wylie is a whistleblower and former employee of the data mining firm Cambridge Analytica, which has come under fire over reports that it swiped the data of about 50 million Facebook users to sway elections. Wylie told NBC’s Meet the Press he plans to meet with “law enforcement and the Department of Justice.”
