Facebook Inc Chief Executive Mark Zuckerberg said on Wednesday that his company made mistakes in mishandling data belonging to 50 million of its users and promised tougher steps to restrict developers access to data.
The world's largest social media network is facing growing government scrutiny in Europe and the United States about a whistleblower's allegations that London-based political consultancy Cambridge Analytica improperly accessed the user information to build profiles on American voters which were later used to help elect U.S. President Donald Trump in 2016.
