Senate Democrats were quick to place the blame on Russia after Facebook’s announcement that a foreign actor waged a coordinated campaign to influence American voters on its site.

The social media company identified a political campaign seeking to sow divisions in the American electorate around #abolishICE and the white supremacist Unite the Right rally. Though Facebook didn’t officially connect the campaign to Russia, it told lawmakers that the techniques used by the fake accounts were similar to those used by Kremlin-backed groups previously, according to the New York Times.
