Mark Zuckerberg has something in common with 87 million other Facebook users: His data was misappropriated, too. 

The Facebook CEO revealed during a House committee hearing on Wednesday that his data was also sold to Cambridge Analytica, among other analytics firms that had access to the information. Facebook discovered that Cambridge Analytica had access to 87 million people's data after Aleksandr Kogan, a lecturer at Cambridge University, sold the firm information gathered from an app called "thisisyourdigitallife."
