Washington, Apr 11: Facebook CEO Mark Zuckerberg on Tuesday testified before the US Congress and said took personal responsibility for the leak of data of tens of millions of its users. Testifying before US senators in the wake of Cambridge Analytica scandal, Zuckerberg said he wants to ensure protection of integrity of elections in India and other countries.

The Facebook founder said that his company will do everything to ensure fair polling takes place in India and other countries. “2018 is an important year for the whole world. Several countries like India, Pakistan will have elections. We’ll do everything possible to ensure these elections are safe,” Zuckerberg said in the joint hearing of the Senate Judiciary and Commerce Committees.

Earlier, the 33-year-old billionaire apologised that Facebook failed to prevent Cambridge Analytica, a data-mining firm affiliated with US President Donald Trump’s election campaign, from gathering personal information from 87 million of its users. He also expressed regret that his company was slow in identifying the Russian operations in 2016, which allegedly benefitted Trump.

Zuckerberg, founder of the world’s most popular social networking website 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.

The hearing is taking place after reports started pouring in March 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 elections.

Zuckerberg added the company was getting to the bottom of exactly what Cambridge Analytica did and telling everyone affected. “What we know now is that Cambridge Analytica improperly accessed information by buying it. When we first contacted Cambridge Analytica, they told us they had deleted the data,” he cleared. (With agency inputs)
