Facebook revealed on Sept. 6 that it had found 470 pages and profiles linked to the Russian troll farm known as the Internet Research Agency.
Facebook on Monday turned over more than 3,000 of the Russia-linked advertisements from its site over to the Senate and House intelligence committees.

The ads and accounts were created to push false information and lies in order to amplify divisive political issues across the political spectrum, including gun rights, gay rights issues and the Black Lives Matter movement.
