Facebook CEO Mark Zuckerberg faced an army of US senators as well as journalist questioning him about Facebook's effots to protect users privacy and how they prevent manipulation of the election by some other countries during a joint hearing of the Senate commerce, science and transportation committee and Senate judiciary committee on Capitol Hill, April 10 2018 in Washington, DC.
And then he continued disclosing that the company is hiring people working on security.
