'Regret Facebook's slow pace in identifying Russia's 2016 operations'

Facebook CEO Mark Zuckerberg, who is testifying in the wake of Facebook's data breach scandal and Russian interference in the 2016 U.S. presidential election, has said that he regretted what happened two years ago.

"This is one of my top priorities is to get this right. One of my greatest regrets is we were slow in identifying the Russian operations in 2016," Zuckerberg said in the joint hearing of the Senate Judiciary and Commerce Committees, at the Capitol Hill here.

His reply came in response to Senator Dianne Feinstein, who asked Zuckerberg what his company was doing to prevent foreign interference in US elections?

The 33-year-old billionaire, in the hearing, also said the Facebook users have full control over their ad experience and they can also turn off the sharing of the information with the third-party.

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.
