Four years after Russia-linked groups stoked divisions in the US presidential election on social media platforms, a new report shows that Moscow's campaign hasn't let up and has become harder to detect.
The report from University of Wisconsin-Madison professor Young Mie Kim found that Russia-linked social media accounts are posting about the same divisive issues – race relations, gun laws and immigration – as they did in 2016, when the Kremlin polluted American voters’ feeds with messages about the presidential election. Facebook has since removed the accounts.
