In an update, Facebook said it found around $100,000 (£76,660) in ad spending from June 2015 to May 2017 was connected to inauthentic accounts affiliated with one another and likely operated out of Russian Federation.
While the "vast majority" of those ads didn't reference any specific presidential candidate, or even the election itself, Stamos explained that the Russian ads that Facebook uncovered were created to amplify hot-button social and political issues, such as LGBT rights, race, immigration and gun rights.
Stamos said about a quarter of the ads identified as tied to Russian Federation were geographically targeted and more ran in 2015 than in 2016.
Facebook admitted to congressional investigators Wednesday that it sold political ads to a Russian firm during the run-up to the 2016 presidential election, according to The Washington Post.
Facebook said that the ad spending was associated with around 3,000 adverts between June 2015 and May 2017 and came from around 470 "inauthentic accounts and pages in violation of our policies", Stamos said.

Facebook said it's continuing to investigate the issue and reported its findings to United States authorities.

In response to these figures, said: "Our analysis suggests these accounts and pages were affiliated with one another and likely operated out of Russian Federation".
