More than 81,000 people have signed a petition calling on Facebook to inform users how they were exposed to “Russian propaganda.”

The change.org petition was started earlier this month by March for Truth. “American citizens that use Facebook deserve to know how they were exposed to Russian disinformation and propaganda,” says a post accompanying the petition. “Facebook should provide this data to users in an application that makes it easy to understand.”

“Users should be able to see how content and advertising messages from identified Russian sources appeared in their timeline, whether they interacted with such media, and basic metrics that quantify their exposure,” it added.

FACEBOOK UNCOVERS $100G IN FAKE AD SPENDING TIED TO RUSSIAN OPERATIVES DURING 2016 ELECTION

The petition’s goal is 150,000 signatures.

Fox News has reached out to Facebook with a request for comment on this story.

Earlier this month, Facebook COO Sheryl Sandberg said Congress should release the ads Russian operatives purchased to the public, while noting that Facebook owed the country an "apology." "Absolutely ... we think it's important they get the whole picture," Sandberg said during an interview with Axios' Mike Allen at the Newseum in Washington, D.C.

On Tuesday Facebook, Twitter and Google will give evidence to a Senate Judiciary Committee investigating “Russian disinformation online.”

FACEBOOK: 150 RUSSIA-LINKED POLITICAL ADS SHOWED UP ON INSTAGRAM

Last month, Facebook announced that it uncovered $100,000 in fake ad spending tied to Russian operatives during the 2016 U.S. Presidential election, associated with around 3,000 ads, which were later turned over to Congress.

Facebook said a Russian group, Internet Research Agency, posted more than 80,000 times on its service during and after the election, potentially reaching as many as 126 million users. The company plans to disclose these numbers to the Senate Judiciary Committee on Tuesday, according to a person familiar with the testimony. The person declined to be named because the committee has not officially released the testimony.

FACEBOOK CEO MARK ZUCKERBERG ASKS FORGIVENESS FOR WAYS HIS 'WORK WAS USED TO DIVIDE PEOPLE'

Twitter plans to tell the same committee that it has uncovered and shut down 2,752 accounts linked to the same group, Russia's Internet Research Agency, known for promoting pro-Russian government positions.

That number is nearly 14 times larger than the number of accounts Twitter handed over to congressional committees three weeks ago, according to a person familiar with the matter. This person requested anonymity because they were not authorized to speak publicly about the new findings ahead of the hearing on Tuesday.

Google announced in a blog post that it found evidence of "limited" misuse of its services by the Russian group, as well as some YouTube channels that were likely backed by Russian agents.

TWITTER BANS ADS FROM RUSSIAN MEDIA OUTLETS RUSSIA TODAY AND SPUTNIK

Last week, Twitter banned ads from Russian media outlets Russia Today (RT) and Sputnik, following the social media giant’s probe into alleged Russian interference in the U.S. election.

RT and Sputnik slammed Twitter’s move.

Twitter also announced a plan to increase ad transparency on its platform, including political and issue-based ads. Facebook CEO Mark Zuckerberg also outlined a plan to bring greater transparency to political ads on the social network.
