Robert Delaware is a US citizen, a former Microsoft contractor, and an avid Freedom of Information Request (FOIA) filer. According to the United States Federal Government however, he's a Russian propaganda agent—at least on Twitter. As part of the social media company's investigation into Russia's meddling into the 2016 US presidential election, it deleted Delaware's account, and sent record of it to US lawmakers as evidence of foreign interference.

The problem is Delaware is actually an American—and has never even been to Russia. So how did his account get swept into a list of those believed to be connected to a Russian troll farm?
