Rep. Dianne Feinstein (D-CA) and Rep. Adam Schiff (D-CA) wrote an open letter to Facebook and Twitter, requesting information on what they claim were Russian bots posting #ReleaseTheMemo on social media.

#ReleaseTheMemo became a trending topic on Twitter last week amid public concern over “alleged Obama-era abuse of government surveillance power.”

Those using the hashtag on Twitter demanded “the release of a four-page memo currently circulating in Congress, allegedly revealing government surveillance abuses under the Foreign Intelligence Surveillance Act (FISA),” which has been described as “shocking,” “alarming,” and “worse than Watergate.”

Feinstein and Schiff, however, claimed it was “Russian bots and trolls,” and not concerned Americans who were posting the hashtag.

In their letter to Facebook and Twitter, the two demanded that the companies “immediately conduct an in-depth forensic examination of the reported actions by Russian bots and trolls surrounding the #ReleaseTheMemo online campaign and how users were exposed to this campaign as a result of Russian efforts.”

“Public reports indicate that accounts linked to the Russian government are again exploiting Twitter and Facebook platforms in an effort to manipulate public opinion,” wrote Feinstein and Schiff in their letter. “That is why we seek your assistance in our efforts to counter Russia’s continuing efforts to manipulate public opinion and undermine American democracy and the rule of law.”

According to the letter:

Specifically, on Thursday, January 18, 2018, the House Permanent Select Committee on Intelligence (HPSCI) Majority voted to allow Members of the U.S. House of Representatives to review a misleading talking points “memo” authored by Republican staff that selectively references and distorts highly classified information. The rushed decision to make this document available to the full House of Representatives was followed quickly by calls from some quarters to release the document to the public. Several Twitter hashtags, including #ReleaseTheMemo, calling for release of these talking points attacking the Mueller investigation were born in the hours after the Committee vote. According to the German Marshall Fund’s Alliance for Securing Democracy, this effort gained the immediate attention and assistance of social media accounts linked to Russian influence operations. By Friday, January 19, 2018, the #ReleaseTheMemo hashtag was “the top trending hashtag among Twitter accounts believed to be operated by Kremlin-linked groups.” Its use had “increased by 286,700 percent” and was being used “100 times more than any other hashtag” by accounts linked to Russian influence campaigns. These accounts are also promoting an offer by WikiLeaks to pay up to $1 million to anyone who leaks this classified partisan memo. If these reports are accurate, we are witnessing an ongoing attack by the Russian government through Kremlin-linked social media actors directly acting to intervene and influence our democratic process. This should be disconcerting to all Americans, but especially your companies as, once again, it appears the vast majority of their efforts are concentrated on your platforms. This latest example of Russian interference is in keeping with Moscow’s concerted, covert, and continuing campaign to manipulate American public opinion and erode trust in our law enforcement and intelligence institutions. We understand Facebook and Twitter have developed significant expertise in identifying inauthentic and malicious accounts. Further, your forensic investigations into Russian government exploitation of your platforms during the 2016 U.S. election have helped expose to the American public the vast extent of Russia’s covert influence efforts. We therefore request that your companies conduct an in-depth forensic examination of this real-time activity on your platforms to determine: Whether and how many accounts linked to Russian influence operations are involved in this campaign;

The frequency and volume of their postings on this topic; and

How many legitimate Twitter and Facebook account holders have been exposed to this campaign.

Given the urgency of this matter, we ask that you provide a public report to Congress and the American public by January 26, 2018. In addition, we urge your companies to immediately take necessary steps to expose and deactivate accounts involved in this influence operation that violate your respective user policies.

Despite the claims in the letter, a report indicates that it was indeed concerned American users who were using the hashtag, and not Russian bots.
