Two months before President Donald Trump’s inauguration, then-President Barack Obama personally warned Facebook Chief Executive Mark Zuckerberg that fake news about the 2016 presidential election had been spread on his social-media site, The Washington Post reported Sunday. At the time ,Zuckerberg reportedly acknowledged the threat of fake news and political disinformation, but said those messages weren’t widespread on Facebook. Last week, however, Zuckerberg admitted to Congress that Facebook had indeed been manipulated and that Russian operatives are suspected to have purchased more than 3,000 politically themed advertisements on the site during the election.
