By now, it’s apparent that Russian agents launched a sophisticated, multi-pronged attack across a wide variety of online platforms to attempt to skew the results of the 2016 election. From purchasing $100,000 in Facebook ads to launching scam Twitter accounts to disseminate misinformation to contracting YouTube vloggers to bash Hillary Clinton, Russian operatives used multiple outlets to knowingly exploit political divisions in the U.S. to their ends. What is becoming more clear, as tech companies gird themselves to answer questions before the Senate Intelligence Committee this week, is the extent to which foreign powers were able to land and manipulate boots on American ground—an effort that, according to a Wall Street Journal report on Monday, involved using Facebook to back more than 60 protest events in the U.S., both before and after the 2016 election.

The new analysis shows that Russian agents’ use of Facebook went far beyond targeted advertising, using Facebook pages and accounts to plan dozens of politically divisive marches, protests, and rallies. Russian-linked “social-media agitators” piggybacked off of the emotionally charged aftermath of shootings in Minneapolis and Dallas in 2016, hosting a rally in support of Philando Castile and a “Blue Lives Matter” protest, respectively, both on July 10. The accounts also organized a candlelight vigil after the shooting at Orlando’s Pulse nightclub, where one victim’s brother spoke. Many of the events, the Journal reports, were not well-attended, but were legitimized thanks to news coverage. (In response to the report, a Facebook spokesman said, “We take this very seriously and that’s why we’re taking strong action to improve security on Facebook by investing in new technology and hiring more people.”)

All eight of the Russia-linked accounts examined by the Journal were included in a recent Facebook sweep, which found 470 accounts belonging to Russian operatives that sought to exploit political divisions among Americans. According to the activists and organizers they contacted, the Facebook page-owners covered costs like equipment rental, and even sent money via services like MoneyGram to organizers in the U.S., though they seemed to lack basic logistical knowledge of events, such as the need to secure permits. The owners of the Facebook pages, which activists say had non-U.S. accents, also seemed anxious to leverage the controversies in order to drum up press. “They’d say, we need to continue to up the protest numbers. We need to continue to get more people to know about us,” Los Angeles-based activist Nolan Hack said of the people representing the Facebook page Black Matters U.S. “I would say—who cares about that? We’re not trying to win a reality show here.”

The protests and marches were not explicitly pro-Trump or anti-Trump. Instead they were intended to deepen existing social divisions—a strategy employed by the same group of Russian agents who impersonated a U.S.-based Muslim nonprofit for more than a year on multiple social-media platforms. This is the second reported instance of Russian trolls successfully communicating with American activists to organize events, suggesting offline efforts that, while smaller in scale, are not insignificant. “Getting someone to physically show up somewhere is huge,” Sarah Oates, a political communications professor, told the Journal. “That is a level of political commitment that is a whole degree stronger than getting someone to comment.”
