Facebook founder and CEO Mark Zuckerberg's own data was swept up in the breach by firm Cambridge Analytica, he said for the first time Wednesday in a hearing before the House Energy and Commerce Committee.

Zuckerberg's second appearance on Capitol Hill this week included many of the same talking points he made Tuesday before two Senate committees. Both times, Zuckerberg apologized for Cambridge Analytica's improper use of personal information from 87 million Facebook users.
"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," he said.
Zuckerberg also addressed other privacy concerns, including what Facebook was doing to improve security around election-related content, specifically ahead of the 2018 midterms. Zuckerberg said earlier this week that as many as 146 million users may have seen content from the Russia-based Internet Research Agency, a troll farm accused of serving up disinformation online to interfere in the 2016 U.S. elections.
