Facebook has shared some details about the Russian-operated profiles it discovered on its platform with Google, as the search giant — with the rest of the tech industry — continues to probe the extent to which Kremlin-backed misinformation spread through their websites during the 2016 U.S. presidential election.
It is unclear if Google has found any suspicious ads or other content after evaluating Facebook's data, an exchange of intel confirmed to Recode today by three sources familiar with the matter. At the very least, Google's investigation appears to be much broader in scope than a similar one by Twitter, which had drawn the ire of Congress for appearing to be incomplete.
