Facebook CEO Mark Zuckerberg apologized for his company’s mistakes in handling users' personal information during a congressional hearing on Tuesday.

Zuckerberg told lawmakers at a joint hearing of the Senate Judiciary and Commerce Committees that “Facebook is an idealistic and optimistic company.” He emphasized that the social network giant have been focused on all the good things that connecting people can do.” However, the company now realized that it didn’t do enough to prevent certain entities from using its tools to do harm.

Zuckerberg accepts responsibility for Facebook’s failures

"That goes for fake news, foreign interference in elections, and hate speech, as well as developers and data privacy. We didn’t take a broad enough view of our responsibility, and that was a big mistake,” said Zuckerberg.

The Facebook CEO accepted responsibility for his company’s missteps. He said, “It was my mistake, and I’m sorry. I started Facebook, I run it, and I’m responsible for what happens here.”

Additionally, Zuckerberg said, “It’s not enough to just connect people. We have to make sure that those connections are positive. It is not enough to just give people a voice. We need to make sure that people aren’t using it to harm other people or to spread misinformation. It is not enough to give people control over their information. We need to make sure that the developers they shared with protect their information too.”

Furthermore, the young tech tycoon emphasized that his company has a “responsibility not just to build tools but to make sure that they are used for good.” He said it will take some time for Facebook to make the necessary changes but he is commitment to correct the company’s failures.

Zuckerberg welcomes “right regulation”

Lawmakers are questioning Zuckerberg over the Cambridge Analytica data scandal. The British political consulting firm, which helped Pres. Trump win the 2016 election, reportedly gained access and improperly used the personal information of up to 87 million FB users.

For months, members of the Congress have been frustrated with Facebook’s lack of control over the spread of Fake news, Russian meddling in the elections, and other misuse of its platform.

During the hearing, Zuckerberg told lawmakers that he welcomes “right regulation” on social media. His company is willing to submit regulatory proposals to the Congress.

Last week, he expressed support for the Honest Ads Act, a legislation that requires disclosures for online political ads. In fact, the social network giant is already implementing a verification process for advertisers seeking to run political ads on its platform. Facebook is also requiring advertisers to label political ads and disclose who paid for them.
