"While Kremlin-aligned agents secretly built fake Facebook groups to foment political division and deployed hordes of Twitter bots to stoke criticism of Hillary Clinton, RT worked out in the open, bolstered by one of the largest online audiences of any news organization in the world and a prominent presence on YouTube’s search results. More than half of American adults say they watch YouTube, and younger viewers are moving to YouTube at staggering numbers,” said Senator Mark Warner, Democrat of Virginia and vice chairman of the Senate Intelligence Committee, which is investigating Russia’s exploitation of social media platforms based in the United States. “YouTube is a target-rich environment for any disinformation campaign — Russian or otherwise — that represents a long-term, next-generation challenge. Much like the Russian-controlled pages on Facebook, RT’s YouTube videos comply with YouTube’s community guidelines, which cover things like nudity, copyright violations and promoting violence against a group based on race or religion. But not propaganda."
