Some of the Trump campaign’s most prominent names and supporters, including Trump’s campaign manager, digital director and son, pushed tweets from professional trolls paid by the Russian government in the heat of the 2016 election campaign.

The Twitter account @Ten_GOP, which called itself the “Unofficial Twitter account of Tennessee Republicans,” was operated from the Kremlin-backed “Russian troll farm,” or Internet Research Agency, a source familiar with the account confirmed with The Daily Beast.

The discovery of the now-unavailable tweets presents the first evidence that several members of the Trump campaign pushed covert Russian propaganda on social media in the run-up to the 2016 election.

President Trump’s son Donald Trump Jr. followed the account until its closure on August 23rd of this year. Trump Jr. retweeted the account three times, including an allegation of voter fraud in Florida one week before the election.

The account notably pushed for Flynn’s reappointment as Trump’s national security advisor, a job Flynn lost after press revelations that he’d lied about his telephone discussions with the Russian ambassador after the election hacks. It also repeatedly pushed Breitbart-backed talking points, including a fake news story about a gang rape in Twin Falls, Idaho that merited dozens of articles from Breitbart News.
