How Russian Trolls Smeared John McCain

An Arizona Republic survey of Sen. John McCain-related tweets collected in an NBC News database of messages finds that Russian accounts routinely spread insults and conspiracy theories smearing McCain as a “traitor” and a “RINO.”

“That the Russian Twitter trolls sought to discredit McCain, R-Ariz., was perhaps predictable given the six-term senator’s longstanding criticism of Russian President Vladimir Putin, who officially sanctioned McCain in 2014.”
