Facebook admitted that up to 87 million users may have had their data hijacked by Cambridge Analytica, which was working for Donald Trump's 2016 presidential campaign.
Facebook on Wednesday said it has suspended more than 400 of thousands of applications it has investigated to determine whether people's personal information was being improperly shared.
Facebook chief Mark Zuckerberg apologized to the European Parliament in May and said the social media giant is taking steps to prevent such a breach from happening again.
Zuckerberg was grilled about the breach in US Congress in April.
