My data was exposed in Cambridge Analytica leak: Zuckerberg

Facebook CEO Mark Zuckerberg, revealed on Wednesday that his own personal data was exposed in the Cambridge Analytica leak among millions of people.

The 33-year-old made the comments in the second and last day of the joint hearing of the members of the US House of Representatives Energy and Commerce Committee at the Capitol Hill.

California Senator Anna Eshoo questioned the social media mogul on whether his data was included in the data sold to the malicious third parties, to which he replied 'yes'.

On the first day of the joint hearing, Zuckerberg told the US Senators that Facebook systems did not see the content of messages being transmitted over WhatsApp.

This confirmation has come as a relief to the messaging app's users, who have been concerned over in the aftermath of data breach scandal.

The 33-year-old also said his company will do everything to ensure fair polling takes place in India and other countries that is happening this year.

The CEO and founder of the world's most popular social networking website also said he was "sorry" that Facebook did not take a "broad enough view" of the responsibility when their platform was being used for circulating fake news and was becoming a tool for foreign interference in elections.

Zuckerberg also expressed regret that his company was slow in identifying the Russian operations in 2016, which allegedly benefitted the then-presidential candidate, Donald Trump, who is now USA's 45th president.

The hearing took place after reports started pouring in last month that the social networking site had compromised with the personal data of over 87 million Facebook users to Britain-based Cambridge Analytica, which allegedly influenced voters during the 2016 US presidential election.
