Mark Zuckerberg is set to return to Capitol Hill on Wednesday, where the Facebook chief executive will face off against a second panel of congressional lawmakers ready to grill him about the social network's privacy practices and efforts to combat disinformation, including Russian propaganda.
"We continue to have these abuses and these data breaches, but at the same time, it doesn't seem like future activities are prevented", DeGette responded.
Facebook uses the data you provide, such as where you live and how old you are, and combines it with geographic information from your phone to tailor ads to a certain audience.
He said that by the end of the year Facebook would have 20,000 people working on security and content review and would also step up use of artificial intelligence to weed out fake accounts and inappropriate content.
He said how Facebook had begun to inform users whether their data was improperly shared with Cambridge Analytica.
CA has been accused of mining personal information of millions of Facebook users illegitimately to help political campaigns and influence polls in several countries.

In a statement following the meeting, described as "robust but constructive", Mr Hancock said: "Social media companies are not above the law and will not be allowed to shirk their responsibilities to our citizens". He said any developer found to be misusing data would be banned.
"You want to present people with the information about what they might be doing and give them the relevant controls in line, at the time that they're making those decisions, not just have it be in the background sometime, or make a one-time decision", he said.
Zuckerberg described Facebook as an "idealistic and optimistic company" which focuses on the positive aspect of connecting people.
He claimed that "there's a very common misperception... that we sell data to advertisers", adding that "we do not sell data to advertisers".
"So we do need to understand whether there was something bad going on at Cambridge University overall that will require a stronger reaction from us".
Senator John Thune, a Republican from South Dakota, asked Zuckerberg if he is willing to make a commitment to protect political speech from "all different corners". "And when we address these challenges, I know we'll look back and view helping people connect and giving more people a voice as a positive force in the world".
It is prescription on how companies treat consumer data.
