Facebook says it will provide the U.S. Congress with copies of some 3,000 advertisements that the social network says were likely bought by people in Russia before and during the 2016 U.S. presidential election.
The world’s largest social network on October 1 said the information would be delivered to Congress on October 2, including related data such as who was targeted and how much each ad cost.
Facebook chief Mark Zuckerberg last month said it would give the information to congressional investigators looking into alleged Russian involvement in the U.S. election, although he did not specify when it would be done.
In its October 1 statement, Facebook said the material would be given to the Senate and House intelligence committees and to the Senate Judiciary Committee.
Facebook previously provided information about Russia-linked ads to U.S. special counsel Robert Mueller, who is also investigating alleged election meddling, people familiar with the matter have told U.S. news agencies.
The social network last month said it had found thousands of ads linked to Facebook accounts that likely operated out of Russia and pushed divisive issues during the campaign.
U.S. intelligence agencies have accused Russia of meddling in the U.S. presidential election to favor Republican Donald Trump over Democratic rival Hillary Clinton.
Moscow has denied the allegations.
