Russia's troll factories were, at one point, likely being paid by the Kremlin to spread pro-Trump propaganda on social media.
That is what freelance journalist Adrian Chen, now a staff writer at The New Yorker, discovered as he was researching Russia's "army of well-paid trolls" for an explosive New York Times Magazine exposé published in June 2015.
"A very interesting thing happened," Chen told Longform's Max Linsky in a podcast in December.
"I created this list of Russian trolls when I was researching. And I check on it once in a while, still. And a lot of them have turned into conservative accounts, like fake conservatives. I don't know what's going on, but they're all tweeting about Donald Trump and stuff," he said.
