The top Democrat on the Senate Intelligence Committee said Tuesday that Facebook’s discovery of a new political influence campaign is “further evidence” that Russia is exploiting social media platforms to spread divisive and misleading content in the U.S.

“Today’s disclosure is further evidence that the Kremlin continues to exploit platforms like Facebook to sow division and spread disinformation,” Sen.

Earlier Tuesday, Facebook disclosed that it found evidence of a coordinated influence campaign involving dozens of fake accounts and pages on its platform. The company has not definitively tied the accounts to Russia but believes Moscow may be involved, according to The New York Times, which first reported on the development.

The company has removed 32 pages and accounts across both Facebook and Instagram as a result of the discovery, and it briefed Congress on the developments this week. Warner said he is “glad that Facebook is taking some steps to pinpoint and address this activity.”

Still, Warner, who has been pushing for legislation to boost transparency of online political advertisements, said he expects Facebook and other social media companies to “continue to identify Russian troll activity and to work with Congress on updating our laws to better protect our democracy in the future.”

Facebook made the discovery as a result of its ongoing investigation into election interference, following Russian attempts to meddle in the 2016 vote. Last year, Facebook discovered that a Russian troll farm known as the Internet Research Agency had purchased $100,000 worth of political ads as part of the broader effort to interfere in the election.

The Senate Intelligence Committee is currently in the final stages of its own investigation into Moscow's meddling in the election. On Wednesday, the committee will hold a public hearing on foreign influence operations and their use of social media platforms, which will feature testimony from experts.
