Facebook says it sold ads to Russian firm

About $100K in political ads bought by ‘troll farm.’

Representatives of Facebook told congressional investigators Wednesday that it has discovered it sold ads during the U.S. presidential election to a shadowy Russian company seeking to target voters, according to several people familiar with the company’s findings.

Facebook officials reported that they traced the ad sales, totaling $100,000, to a Russian “troll farm” with a history of pushing pro-Kremlin propaganda, these people said.

A small portion of the ads, which began appearing in the summer of 2015, directly named Republican nominee Donald Trump and Democrat Hillary Clinton, the people said. Most of the ads focused on politically divisive issues such as gun rights and immigration fears, as well as gay rights and racial discrimination.

The acknowledgment by Facebook comes as congressional investigators and special counsel Robert Mueller are probing Russian interference in the U.S. election, including allegations that the Kremlin may have coordinated with the Trump campaign.

The U.S. intelligence community concluded in January that Russia had interfered in the U.S. election to help elect Trump, including by using paid social media trolls to spread fake news intended to influence public opinion.

Even though the ad spending from Russia is tiny relative to overall campaign costs, the report from Facebook that a Russian firm was able to target political messages is likely to fuel pointed questions from investigators about whether the Russians received guidance from people in the United States — a question some Democrats have been asking for months.

An official familiar with Facebook’s internal investigation said the company does not have the ability to determine whether the ads it sold represented any sort of coordination.

The acknowledgment by Facebook follows months of criticism that the social media company served as a platform for the spread of false information before the November election.
