Facebook handed Russia-linked ads over to Mueller under search warrant
(CNN Money) — Special counsel Robert Mueller and his team are now in possession of Russian-linked ads run on Facebook during the presidential election, after they obtained a search warrant for the information.
Facebook gave Mueller and his team copies of ads and related information it discovered on its site linked to a Russian troll farm, as well as detailed information about the accounts that bought the ads and the way the ads were targeted at American Facebook users, a source with knowledge of the matter told CNN.
(On Sunday, Facebook told CNN in a statement that it was providing information to Mueller, “including ads and related account information.”)
The disclosure, first reported by the Wall Street Journal, may give Mueller’s office a fuller picture of who was behind the ad buys and how the ads may have influenced voter sentiment during the 2016 election.
“We continue to work with the appropriate investigative authorities,” Facebook said in a statement to CNN.
Facebook informed Congress last week that it had identified 3,000 ads that ran between June 2015 and May 2017 that were linked to fake accounts. Those accounts, in turn, were linked to the pro-Kremlin troll farm known as the Internet Research Agency.
In those briefings, Facebook spoke only in generalities about the ad buys, leaving some committee members feeling frustrated with Facebook’s level of cooperation.
Sen. Mark Warner, the top Democrat on the Senate Intelligence Committee, told CNN last week that Facebook had not turned over the ads to Congress. Warner has also called Facebook’s review “the tip of the iceberg,” and suggested that more work needs to be done in order to ascertain the full scope of Russia’s use of social media.
Warner also indicated that his committee may call Facebook, Twitter and other social media networks in for “some level of public hearing.”
As CNN reported Thursday, Facebook is still not sure whether pro-Kremlin groups may have made other ad buys intended to influence American politics that it simply hasn’t discovered yet. It is even possible that unidentified ad buys may still exist on the social media network today.
The special counsel’s spokesman declined to comment.
