The "information war" against Russia makes any efforts to improve the country's image in the West futile, a Kremlin spokesman said Thursday after the U.S. public relations firm Ketchum said its contract with the Russian government had ended.

The New York Times op-ed that has much of the country — including Washington — abuzz on Thursday was placed there by Ketchum, a public-relations giant with a long history of dealings with the Russian government. A spokeswoman for Ketchum confirmed a report from BuzzFeed's Rosie Gray that the firm submitted Russian President Vladimir Putin's piece to the Times, and that Putin himself wrote the op-ed.

Today, Vladimir Putin wrote an op-ed about Syria in the New York Times. The piece was placed by the public-relations giant Ketchum, Buzzfeed reported. On Nov. 16, 2012, we explored how Ketchum placed pro-Russia op-eds in American publications by businesspeople and others without disclosing the role of the Russian government. Ketchum's latest public filing says it was paid $1.9 million by Russia for the six-month period ending May 31, 2013. It received another $3.7 million for its work for Russian energy giant Gazprom over the same period. Here is our original report.
