When Facebook Chief Mark Zuckerberg meets with European officials on Tuesday, he is set to testify that the social networking giant did not do enough to prevent its tools from causing "harm."

"It's also become clear over the last couple of years that we haven't done enough to prevent the tools we've built from being used for harm," Zuckerberg said in remarks prepared for European officials and obtained by NBC News.
