Facebook Documents Accelerate EU Push to Regulate Social Media

European officials are seizing on disclosures from Facebook whistleblower Frances Haugen to accelerate and sharpen their plans to impose sweeping new restrictions on big technology companies.

After a series of meetings with Ms. Haugen, policy makers and lawmakers for the European Union said that the bloc must move quickly to toughen and enact measures in a bill proposed last year that would impose stiffer obligations on social-media services. The bill, as currently drafted, would require large tech platforms to actively look for and mitigate risks from content that is illegal, or face hefty fines.
