Washington - Facebook founder and chief executive Mark Zuckerberg is facing intensified calls to appear in person at investigations into the social network's conduct.
His company has been accused of failing to properly inform users that their profile information may have been obtained and kept by Cambridge Analytica, a data firm widely-credited with helping Donald Trump win the 2016 US presidential election.
Facebook said on Friday it had blocked Cambridge Analytica from Facebook while it investigated claims the London-based firm did not, as promised, delete data that was allegedly obtained using methods that were in violation of Facebook's policies.
Both Cambridge Analytica and Facebook deny any wrongdoing.
Despite pledging that in 2018 he would "fix" his company, Facebook founder Mark Zuckerberg has managed to avoid engaging with the site's growing number of critics - instead sending lawyers or policy bosses to various committee hearings.
The 33-year-old's recent remarks on some of Facebook's controversies have been communicated in the relatively safe space of a blog post or video message published on his Facebook page. (FA)
