WASHINGTON (AP) — Tech giants Facebook, Twitter and Google are set to go before senators Tuesday to defend their security measures as new revelations have emerged that Russian-linked accounts reached many more American voters than previously thought.
Testimony from Facebook obtained by The Associated Press on Monday revealed that posts generated by a Russian internet agency potentially reached as many as 126 million users. In the testimony, the company said that pages created by Russia's Internet Research Agency generated 80,000 posts on 120 pages between January 2015 and August 2017. Possible views reached the millions after people liked the posts and shared them.
Colin Stretch, Facebook's general counsel, plans to disclose the new numbers to Congress in testimony to a Senate Judiciary subcommittee on Tuesday, according to a source familiar with the testimony. The person declined to be named because the committee has not officially released it. Facebook, along with Twitter and Google, are set to testify at three hearings Tuesday and Wednesday as part of congressional probes of Russian election interference.
Stretch's testimony makes clear that many of those users may never have seen the material. The company says the total number represents around 1 out of 23,000 pieces of content on the site.
These "organic" posts that appeared in Facebook users' news feeds are distinct from more than 3,000 advertisements linked to the agency that Facebook has already turned over to congressional committees. The ads — many of which focused on divisive social issues — pointed people to the agency's pages, where they could then like or share its material.
Twitter plans to tell the same subcommittee that it has uncovered and shut down 2,752 accounts linked to the same group, Russia's Internet Research Agency, which is known for promoting pro-Russian government positions.
That number is nearly 14 times larger than the number of accounts Twitter handed over to congressional committees three weeks ago, according to a person familiar with the matter. This person requested anonymity because they were not authorized to speak publicly about the new findings ahead of the hearing on Tuesday.
And Google announced in a blog post that it found evidence of "limited" misuse of its services by the Russian group, as well as some YouTube channels that were likely backed by Russian agents.
Lawmakers have pressured the social media companies to come forward and have criticized them for not being fully forthcoming immediately after the election. All three firms are expected to face questions about what evidence of Russian interference they found on their services, as well as why they didn't find it earlier.
Lawmakers are also expected to probe whether the firms know of any connections between the Russian posts and the Trump campaign.
South Carolina Sen. Lindsey Graham, the Republican chairman of the Judiciary subcommittee holding the hearing, said in a statement that manipulation of social media by terrorist organizations and foreign governments is "one of the greatest challenges to American democracy" and he wants to make sure the companies are doing everything possible to combat it.
"Clearly, to date, their efforts have been unsuccessful," Graham said.
On Twitter, the Russia-linked accounts put out 1.4 million election-related tweets from September through Nov. 15 last year — nearly half of them automated. The company also found nine Russian accounts that bought ads, most of which came from the state-backed news service Russia Today, or RT.
Twitter said last week it would no longer accept ads from RT and Sputnik, another state-sponsored news outlet. It will donate the $1.9 million it has earned from RT since 2011 to support external research into political uses of Twitter.
Google said that two accounts linked to the Russian group spent $4,700 on ads its platforms during the 2016 election. The company also found 18 YouTube channels likely backed by Russian agents. Those channels hosted 1,108 videos with 43 hours of material, although they racked up just 309,000 views in the U.S. between June 2015 and November 2016, Google said.
The companies will almost certainly do what they can to convince lawmakers that they can fix the problem on their own, without the need for regulation. A bill unveiled earlier this month would require social media companies to keep public files of election ads and require companies to "make reasonable efforts" to make sure that foreign individuals or entities are not purchasing political advertisements in order to influence Americans.
The companies haven't commented on the proposed legislation, but say they're at work on the problem. Last week Facebook said it will verify political ad buyers in federal elections and build transparency tools to link ads to the Facebook pages of their sponsors. Twitter has also said it will require election-related ads for candidates to disclose who is paying for them and how they are targeted.
Google announced on Monday that it will also verify the identity of election-related ad buyers and identify these advertisers publicly via an ad icon. It will provide a public database of election ads detailing who purchased each one, and will publish a transparency report on election ads as well.
