A Russian computer expert accused of meddling in the US 2016 presidential election says he simply did ordinary IT work, not political trolling, BBC reports.
Sergei Polozov is among 13 Russians named in the Mueller indictment, which alleges a systematic Russian state effort to influence US voters.
Mr Polozov told BBC Russian he knew nothing about a Russian "troll farm" called the Internet Research Agency.
The agency's alleged location, he said, was a business centre he had visited.
"My job was typical of co-operation between an IT company and any subcontractor: you are set a task, for example, to create a website, a visiting card, a web page."
None of those tasks, he stressed, involved use of the English language or targets in the US.
