(credit: Marco Paköeningrat) Facebook has confirmed a Washington Post report indicating that its ad sales team had sold advertising to a "shadowy Russian company" ahead of the 2016 Presidential election. These sponsored FB posts, in turn, were used to "target" American voters, either by directly naming presidential candidates or by focusing on "politically divisive issues." This information was disclosed to congressional investigators, according to "several people familiar with the company’s findings," after an internal Facebook investigation this spring linked $100,000 of ad buys to a Russian company known as the Internet Research Agency.
