From the Senate Intelligence Committee:
The Committee found that Russia's targeting of the 2016 U.S. presidential election was part of a broader, sophisticated, and ongoing information warfare campaign designed to sow discord in American politics and society. Moreover, the IRA conducted a vastly more complex and strategic assault on the United States than was initially understood.
The IR.A's actions in 2016 represent only the latest installment in an increasingly brazen
interference by the Kremlin on the citizens and democratic institutions of the United
States.
...
One communication obtained by the Committee details an IRA employee's description of Election Day 2016, from the vantage of an information warfare operative: "On November 9, 2016, a sleepless night was ahead of us. And when around 8 a.m. the most ' important result of our work arrived, we uncorked a tiny bottle of champagne ... took one gulp each and looked into each other's eyes .... We uttered almost in unison: 'We. made America great."
Further, the IRA's attempts to engage political activists by using false U.S. personas
to "communicate with unwitting members, volunteers, and supporters of the Trump Campaign involved in local community outreach, as well as grassroots groups that supported then-candidate Trump."
