Facebook will let users see what pages and Instagram accounts they followed that are linked to supposed Russian propaganda efforts. The company took this step as part of a request from the US Congress. Facebook, Google, and Twitter have testified in front of the US Senate regarding Russia’s meddling in the 2016 US presidential election. The companies admitted that Russia-linked parties bought ads and created fake accounts on their networks to push divisive and incendiary topics such as race relations, religion, immigration, and gun rights. Facebook said as many as 126 million users were served posts on Facebook and 20 million users on Instagram.
