Russia's influence campaign on Twitter pushed pro-gun and pro-National Rifle Association messages during the 2016 election and beyond — a rare example of consistency in a scheme that mostly sought to play up extremes on the left and right.

They provided NPR with a list of posts made by the Internet Research Agency that related to guns and the National Rifle Association. That data was then analyzed to assess the Russian troll farm's messaging and its influence.
