Facebook says it identifies campaign to meddle in 2018 U.S. elections

(Adds comments from declared administrator of Resisters Facebook page, paragraphs 13-16)

July 31 (Reuters) - Facebook Inc said on Tuesday it had identified a new coordinated political influence campaign to mislead its users and sow dissension among voters ahead of November's U.S. congressional elections.

It said it had removed 32 pages and accounts from Facebook and Instagram, part of an effort to combat foreign meddling in U.S. elections.

The company stopped short of identifying the source of the misinformation. But members of Congress who had been briefed by Facebook on the matter said the methodology of the influence campaign suggested Russian involvement.

“I can say I think with pretty high confidence I think this is Russian-related,” Senator Mark Warner, the top Democrat on the Senate Intelligence Committee, told reporters at the U.S. Capitol.

Two U.S. intelligence officials told Reuters there was not sufficient evidence to conclude that Russia was behind the Facebook campaign, but one noted that “the similarities, aims and methodology relative to the 2016 Russian campaign are quite striking."

A Russian propaganda arm tried to tamper in the 2016 U.S. election by posting and buying ads on Facebook, according to the company and U.S. intelligence agencies. In February, the U.S. Justice Department indicted 13 Russian nationals, and the St. Petersburg-based Internet Research Agency, for interfering in the 2016 U.S. election.

Moscow has denied involvement.

Facebook has been on the defensive about influence activity on its site and concerns over user privacy tied to long-standing agreements with developers that allowed them access to private user data.

'ARMS RACE'

The Atlantic Council’s Digital Forensics Research Lab, which was shown the suspended pages ahead of the takedown, said they showed similarities in language and approach to previously fake accounts from the Internet Research Agency, which is known as the “troll factory” because it stirs up public opinion on social media sites.

The lab cited “consistent mistranslation, as well as an overwhelming focus on polarizing issues at the top of any given news cycle.” It said, for example, the posts on the year-old, feminist Resisters page “took a liberal or left-wing stance on issues around gender, race, immigration, and human rights.” Other pages promoted racial pride among minority groups.

The group said the Resisters page was alarming because it was pushing for confrontation at multiple protests, including against "Unite the Right 2," with a potential for violence.
