Facebook has told authorities investigating Russia's influence on the 2016 election about thousands of ads likely linked to Russia, many of which were connected to "inauthentic" accounts and Pages and focused on drawing attention to divisive social issues.
Why it matters: Congressional investigators — particularly Senate Intel Committee Vice Chair Mark Warner — have raised concerns about the possibility that Facebook's ad targeting tools could have been used to boost the spread of so-called "fake news" with the intention of influencing the election. That's raised questions about whether the Trump campaign could have worked with Russian actors to target that content.
This marks a shift for Facebook: Back in July, a company spokesperson told CNN said, "we have seen no evidence that Russian actors bought ads on Facebook in connection with the election." Importantly, the company isn't claiming to have uncovered any Russian government involvement with the accounts.
