Facebook founder Mark Zuckerberg stops at Pat's King of Steaks in Philadelphia

Facebook's role in the alleged Russian interference campaign has come under renewed scrutiny in recent weeks, with the Daily Beast reporting earlier in September that Russian operatives masquerading as a US group organized an anti-immigrant protest in Idaho during the election.

Since average users "don't know if you're seeing the same messages as everyone else", Zuckerberg said, Facebook will "make it so you can visit an advertiser's page and see the ads they're now running to any audience on Facebook". When someone buys political ads on TV or other media, they are required by law to disclose who paid for them.

The 3,000 ads included some that highlighted support for Democrat Hillary Clinton among Muslim women, as well as others that showed a deep understanding of US social divides, the Washington Post reported on Monday.

"We believe in the power of democracy, which is why we're taking this work on elections integrity so seriously, and have come forward at every opportunity to share what we've found", Elliot Schrage, vice president for public policy and communications, said in a statement following WaPo's story. "That is an assessment that can be made only by investigators with access to classified intelligence and information from all relevant companies and industries - and we want to do our part".

Former US president Barack Obama discussed fake news with Mark Zuckerberg in Peru a year ago.

At the moment, it's also unclear how much of the USA government's investigation into Russian hacking attacks explored Facebook, and what it may have found.

Alongside its announcement about sharing information with Congress, Facebook released a promise to continue its internal investigation into misuse of its platform and a commitment to greater transparency in the ads it runs.

The bill would also apply to other popular social media outlets like Twitter, which is meeting with the Senate intelligence committee next week. In a sense, this plan would solidify CEO Mark Zuckerberg's control over the company with a focus on the long-term management of Facebook. The first word that the federal governmental was investigating Russia's influence in the campaign came in July 2016, a few weeks after Guccifer 2.0's first post-in which he tries to claim sole credit for hacking the Democratic National Committee.
