In testimony before Congress, Facebook CEO Mark Zuckerberg acknowledged the company's partnership with special counsel Robert Mueller.
Sen. Ted Cruz of Texas accused Facebook of bias shutting out conservative voices, saying the firm had 'blocked' Trump-loving performers Diamond & Silk from its site. The duo who were regulars at Trump campaign rallies wrote tweeted that Facebook had sent them a message saying: 'The Policy team has came to the conclusion that your content and your brand has been determined unsafe to the community.'
Last year Facebook limited distribution of their content, but did not shut down their page, the Wall Street Journal reported.
Zuckerberg was in Washington to address lawmakers in a packed hearing room inside the underground Capitol Visitors Center in one of the year's most closely-watched hearings.
The 33-year tried to make inroads with some of the lawmakers who will sit on the dais for the televised spectacle – weeks after revelations of the massive extent of a security breakdown that allowed tens of millions of users have personal data get into the hands of consulting firm Cambridge Analytica.
The daily revelations set up Zuckerberg to draw fire both from Republicans who are hearing concerns from their millions of constituents and Democrats who infuriated about how Russian efforts to try to tilt the elections took advantage of the site.
Lawmakers from two Senate committees, representing almost half the Senate, will get a crack at questioning him.
In just a small taste of what Zuckerberg will have to endure, Delaware Democratic Sen. Chris Coons complained that there were took fake Facebook accounts pretending to be him – with Russia connections on display.
Zuckerberg defended Facebook as an 'idealistic and optimistic' company, before accepting personal responsibility for not setting up the right security protocols.
'It was my mistake, and I'm sorry,' he said, in House testimony released a day before his first grilling.
'But it's clear now that we didn't do enough to prevent these tools from being used for harm as well,' according to Zuckerberg's prepared testimony.
'That goes for fake news, foreign interference in elections, and hate speech, as well as developers and data privacy.'
He continued: 'We didn't take a broad enough view of our responsibility, and that was a big mistake. It was my mistake, and I'm sorry. I started Facebook, I run it, and I'm responsible for what happens here.
'So now we have to go through every part of our relationship with people and make sure we're taking a broad enough view of our responsibility,' he pledged.
After mentioning the estimated 126 million people who got content linked to the infamous Russian troll farm Internet Research Ageny, Zuckerber wrote: 'There's no question that we should have spotted Russian interference earlier.'
在提及1.26亿用户收到俄罗斯公司Internet Research Ageny的挑衅信息时，扎克伯格写到：“我们确实应该早些发现俄罗斯的干涉行为，是我们的过失。”
Zuckerberg is trying to earn some 'likes' from lawmakers, meeting privately Monday with some of those who will question him on the firm's privacy scandal later this week.
Zuckerberg said in a conference call with reporters last week that he accepted blame for the data leak, which has angered users, advertisers and lawmakers, while also saying he was still the right person to head the company he founded.
On Friday, Facebook backed proposed legislation requiring social media sites to disclose the identities of buyers of online political campaign ads and introduced a new verification process for people buying 'issue' ads.
The steps are designed to deter the kind of election meddling and online information warfare that U.S. authorities have accused Russia of pursuing, Zuckerberg said on Friday. Moscow has denied the allegations.
In February, U.S. Special Counsel Robert Mueller charged 13 Russians and three Russian companies with interfering in the 2016 U.S. presidential election by sowing discord on social media.
Zuckerberg, on the call with reporters, said Facebook should have done more to audit and oversee third-party app developers like the one hired by Cambridge Analytica in 2014.
