Adam Berry/Getty Images A series of developments on Wednesday shed new light on the lengths Russia went to exploit social media, and Facebook in particular, to spread disinformation and generate political division among the American public. Facebook recently came under the microscope after it emerged earlier this month that fake accounts linked to Russian entities used the platform to spread fake news and bought $100,000 worth of divisive ads leading up to the 2016 election. The company still does not know the extent of Russia's ad purchases or whether these unidentified ad buys are still on the site.
