Mark Zuckerberg addressed members of the European Parliament in Brussels on Tuesday, continuing an apology-and-explanation tour the Facebook CEO kicked off last month when he testified before the U.S. Congress .

The European and U.S. inquiries concern the same fundamental questions about the social media giant, triggered by the news that Facebook permitted Cambridge Analytica to harvest the private data of 87 million users and that Facebook failed to take action when it became clear in 2016 that foreign actors were using its platform to spread disinformation and undermine democratic processes.

Heres Zuckerbergs defense, in short: Oeps! Het spijt me! Thats Flemish for Whoops! I am very sorry!

In his opening statement Tuesday, Zuckerberg reiterated whats become a common refrain, acknowledging both that his company failed to properly safeguard its users data and that it was caught unprepared to counteract political meddling during past elections. As hes done before, he assured the European politicians that Facebook now takes both issues seriously, but he stopped short of promising they wont arise again.

Zuckerberg was originally scheduled to speak privately, but agreed to have the questioning streamed online under pressure from European Parliament President Antonio Tajani.

Some of the sharpest queries came from Belgian member Guy Verhofstadt, who called out Zuckerberg for Facebooks long history of apologizing for its mistakes and then failing to actually correct them. He noted the similarities between Facebook and the global banking system, which assured watchdogs in 2006 that it was doing a great job of self-regulation. A historic global recession soon followed, set off by banking malfeasance.

I really think we have a big problem here and its not solved by saying, Were going to fix it ourselves, Verhofstadt said.

Then he asked Zuckerberg directly if he wants to be remembered, together with Steve Jobs and Bill Gates, as having enriched our world and societies or if he wants to simply be the genius that created a digital monster that is destroying our democracies and our societies.

The meeting constituted Zuckerbergs sole address to European politicians ahead of the May 25 implementation date for strict new data privacy rules under the European Unions General Data Protection Regulation . Zuckerberg declined an invitation to separately address lawmakers in the U.K., where Facebook is under fire for its role in the countrys 2016 vote to leave the EU.

Unlike his testimony in the U.S., where members of Congress took turns questioning Zuckerberg and hearing his answers, the European politicians all spoke first and then Zuckerberg addressed their questions in one long statement at the end. That format proved problematic, as several members objected when he ignored the specifics and stuck to discussing their high level concerns.

Pressed for greater detail toward the end, including on the companys practice of tracking people who dont even have Facebook profiles, Zuckerberg promised to follow up with the politicians at a later date.
