On April 18, the guests on “Studio One,” a political talk show on Russian state television’s Channel One, discussed North Korea’s failed test firing of a missile and the U.S. response. Among the experts taking part in the discussion was a person identified as an American journalist named Greg Vainer.

Opening the show – which on this day was headlined – Studio One host Artem Sheinin asked: “Do you know what is the best way to determine if some political event really disturbs people? …When you get a phone call in the studio and the people on the other end tell you: ‘Hi, we are on vacation but we are very much concerned about Trump’s aggressive behavior with North Korea! Explain to us – will there be World War III or should we be planting our garden?’”

“The White House right now is considering a very different scenario, and I will tell you what it is if you promise to keep it a secret,” said one of the guests, identified as “Greg Vainer, journalist (U.S.).” Speaking Russian without the hint of an accent, Vainer continued: “There will be a trade quarantine introduced against North Korea.”

The host interrupted: “Wait, on what side does the U.S. border North Korea to be able to impose such a quarantine?”

As Vainer mumbled that China is also on board for the quarantine, all the other guests simultaneously started arguing with him. The host, meanwhile, started speaking about “historical” parallels – how the U.S. “pushed us, the Soviet Union, to self-destruction, and then pushed Iraq, so it’s taken over by ISIS, just like they are now pushing North Korea for no obvious reason.”

As the program proceeds, the “American journalist” is repeatedly the target of arguments that the Russian guests inevitably win.

However, Gennady Katsov, a Russian journalist based in New York, has identified “Greg Vainer” as a long-time acquaintance named Gregory Vinnikov. In a , Katsov described Vinnikov as a former businessman and the owner of the Eastern Tours Agency in New York City – who, Katsov said, “stole millions of dollars from his clients and fled to Saint Petersburg, Russia.”

Katsov also posted a link to the Facebook profile of , whose profile photo shows someone identical to the man identified on Russian TV as Greg Vainer.

The Moscow Times, an independent English-language newspaper in the Russian capital, ran a front-page last week, which was headlined: “Russian TV Passes Off Corrupt Petersburg Entrepreneur as ‘American Journalist’.”

By his own account, Gregory Vinnikov immigrated to the U.S. in 1980. It is not clear whether he was granted or even ever applied for U.S. citizenship.

According to publicly available tax reports, Vinnikov owns a three-bedroom apartment in New Jersey in a high-end neighborhood across the Hudson River from Manhattan. According to New Jersey voter registration data, Vinnikov has never registered as voter in his state of residence or any other U.S. state.

The Republican Party’s press office also confirmed to Polygraph.info that Vinnikov is not a member of the Republican National Committee.

From publicly available court information, two of the New Jersey court cases resulted in monetary judgments for $14,000. Those cases remain open, meaning that Vinnikov has not repaid those debts.

In New York, two court cases were brought against Vinnikov by American Express Bank, FSB. One of these, involving failure to pay $9,087.59, was settled on August 30, 2012. The other New York case, according to court data, is still “active.”
