Twitter has uncovered and suspended 2,752 accounts — many of them automated — that are linked to to Russia’s Internet Research Agency.

The Russian propaganda accounts issued a total of 1.4 million tweets during the 2016 presidential election, the social media company plans to reveal in congressional testimony.

The updated number of Russia-linked troll accounts is 14 times larger than the 201 accounts the company originally told Congress had utilized their site during a September testimony on the matter.

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.
