Facebook CEO Mark Zuckerberg kicked off his second day of testimony in Congress on Wednesday by apologizing to House members about the Cambridge Analytica scandal, in the same words he had used in the Senate the day before.
"We didn’t take a broad enough view of our responsibility, and that was a big mistake," he said. "It was my mistake, and I’m sorry. I started Facebook, I run it, and I’m responsible for what happens here."
Zuckerberg stuck to that message during nearly five hours of testimony Tuesday at a marathon Senate hearing, in which he took questions about data privacy, Russian election interference and conservative allegations of Facebook political bias, among other topics.
House Energy & Commerce Chairman Greg Walden (R-Ore.) opened the hearing by saying he's concerned about the company's business model.
"While Facebook has certainly grown, I worry it has not matured. I think it is time to ask whether Facebook may have moved too fast and broken too many things," Walden said. "There are critical, unanswered questions surrounding Facebook’s business model and the entire digital ecosystem regarding online privacy and consumer protection."
The lawmaker's questions, though, quickly jumped into a range of topics, from Facebook's treatment of a pair of conservative social media stars to whether the social network allows discriminatory housing ads.
