Cambridge Analytica said Monday whistleblower Christopher Wylie is "misrepresenting himself and the company" in weekend reports alleging massive mishandling of Facebook user data.

"Cambridge Analytica strongly denies the claims recently made by the New York Times, the Guardian and Channel 4 News," the conservative research firm said in a statement.

"The company's detailed responses to their questions ahead of publication were largely ignored in their subsequent reporting. Their source is a former contractor for Cambridge Analytica – not a founder as has been claimed – who left in 2014," the company said. Wylie did not immediately respond to a request for comment.

The research firm with ties to Donald Trump and his presidential campaign allegedly gained access to data from 50 million Facebook profiles collected by Aleksandr Kogan through a psychology test quiz.
