Facebook Inc. has begun overhauling how it handles political ads on its platform and may put some changes in place before USA elections next year, Facebook's chief technology officer said on Wednesday.
The question of overlap is of potential significance for special counsel Robert Mueller and congressional investigators as they look for evidence of collusion between the Russians and the Trump campaign.
Twitter and Facebook have said Russian Federation bought ads and had accounts on their platforms.
While Facebook's chief operating officer, Sheryl Sandberg, now favours the release, she didn't say Thursday when the company would do so. She is expected to give a live interview with the news website Axios on Thursday.
House lawmakers investigating Russia's suspected meddling in the 2016 USA presidential election are hoping to release copies of the 3,000 Facebook ads purchased by Kremlin-aligned agents and trolls.
Meanwhile, the United Kingdom government has suggested regulating Facebook and Google as media companies and publishers, which would make them legally responsible for the content posted on their platforms.
Disclosures by Facebook, Twitter Inc. and Alphabet Inc.'s Google that their products were battlegrounds for Russian election meddling past year have turned into a crisis for Silicon Valley.
Wednesday's meetings are ahead of a November 1 House Intelligence Committee hearing at which Facebook, Twitter and Google are expected to testify.
The move comes as critics and lawmakers are increasingly calling for the regulation of Facebook and other internet giants. "But what we really owe the American people is determination to do a better job of preventing foreign meddling", she said.
Sandberg acknowledged that the company had erred in how it handled the issue of foreign interference a year ago.
The group will focus its dialogue with Sandberg on Facebook's "diversity tone-deafness", including why the company has no black members of its board of directors, why Facebook allowed communities of to be targeted with its advertising products and who is being held accountable to make sure that such ads don't appear on Facebook in the future.
"We take reports of misuse of our platform seriously".
She also criticized Twitter's decision this week to remove a campaign video from Republican Representative Marsha Blackburn, who is running for Senate in Tennessee.
"In that ad, there are a lot of things that people don't like, that I don't like".
Sandberg's comments come a day after the outgoing boss of the UK's media regulator, Dame Patricia Hodgson, said both Google and Facebook were publishers in her view.
