In early 2022, a young couple from Canada, Lauren Chen and Liam Donovan, registered a new company in Tennessee that went on to create a social media outlet called Tenet Media.

By November 2023, they had assembled a lineup of major conservative social media stars, including Benny Johnson, Tim Pool and Dave Rubin, to post original content on Tenet’s platform. The site then began posting hundreds of videos — trafficking in pointed political commentary as well as conspiracy theories about election fraud, Covid-19, immigrants and Russia’s war with Ukraine — that were then promoted across the spectrum of social media, from YouTube to TikTok, X, Facebook, Instagram and Rumble.

It was all, federal prosecutors now say, a covert Russian influence operation. On Wednesday, the Justice Department accused two Russians of helping orchestrate $10 million in payments to Tenet in a scheme to use those stars to spread Kremlin-friendly messages.

The disclosures reflect the growing sophistication of the Kremlin’s longstanding efforts to shape American public opinion and advance Russia’s geopolitical goals, which include, according to American intelligence assessments, the election of former President Donald J. Trump in November.

In 2016 and 2020, Russia employed armies of internet trolls, fake accounts and bot farms to try to reach American audiences, with debatable success. The operation that prosecutors described this week shows a pivot to exploiting already established social media influencers, who, in this case, generated as many as 16 million views on Tenet’s YouTube channel alone.
