Google has found evidence that Russian agents bought ads on its wide-ranging networks in an effort to interfere with the 2016 presidential campaign.

Using accounts believed to be connected to the Russian government, the agents purchased $4,700 worth of search ads and more traditional display ads, according to a person familiar with the company’s ongoing internal investigation who was not allowed to speak about it publicly.
