There's been a lot of fuss over a Russian group buying Facebook ads in the run-up to the 2016 presidential election, to the point where it's handing the ads to Congress as it investigates the scope of Russia's influence campaign. But what's in those ads, exactly? We might have a better idea. Washington Post sources say that the 3,000 ads headed to Congress were built to exploit American social divisions. Some championed activist groups like Black Lives Matter, while others portrayed them as existential threats. Others aimed to split opinions through hot-button issues like Islam, LGBT rights, gun rights and immigration.
