WASHINGTON: Facebook said on Sunday it was conducting a "comprehensive internal and external review" to determine if the personal data of 50 million users that was reported to be misused by a political consultant still existed.

The company said in a statement that it was trying to determine the accuracy of allegations that a researcher gave the firm Cambridge Analytica inappropriately obtained Facebook user data starting in 2014.
