Some of the ads purchased by a Russian "troll farm" from Facebook were also seen on Instagram during the 2016 election, Facebook revealed Friday.

Out of the 3,000 advertisements purchased by a Russian group with connections to the Kremlin, approximately 5 percent were viewed on Instagram. Facebook noted that approximately $6,700 out of the total $100,000 the group spent on ads was used to ads on Instagram.

Facebook announced Monday approximately 10 million people saw at least one of the ads. Additionally, 44 percent of the ads were viewed prior to the 2016 election on Nov. 8, and 56 percent were seen after the election, meaning interference extended past the campaign and may continue into the present.

Facebook turned over the ads connected to the Kremlin to Congress on Monday and previously disclosed descriptions of the ads to special counsel Robert Mueller, who is investigating Russian interference in the 2016 election.

Facebook announced last month $100,000 was purchased for ads from June 2015 to May 2017 by a Russian group called the Internet Research Agency, which has promoted pro-Russia propaganda. The money was affiliated with approximately 3,000 ads and 470 "inauthentic accounts and pages."

Facebook then suspended all 470 accounts connected to the ads because they did not adhere to authenticity requirements.

Facebook unveiled Monday it would implement additional steps designed to improve transparency of advertisements.

The Senate Intelligence Committee has requested representatives from Facebook, Twitter, and Alphabet, Google's parent company, to testify at a public hearing on Nov. 1. Facebook and Twitter have confirmed they will participate.
