As for what Facebook can do at this point, Zuckerberg pledged to "bring Facebook to an even higher standard of transparency" regarding political ads. "Not only will you have to disclose which page paid for an ad, but we will also make it so you can visit an advertiser's page and see the ads they're currently running to any audience on Facebook," said the Facebook CEO.

Two weeks ago, we announced we had found more than 3,000 ads addressing social and political issues that ran in the US between 2015 and 2017 and that appear to have come from accounts associated with a Russian entity known as the Internet Research Agency. In a blog post published Thursday afternoon, Facebook general counsel Colin Stretch said, “We believe it is vitally important that government authorities have the information they need to deliver to the public a full assessment of what happened in the 2016 election.”

“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,” the post read. Zuckerberg didn't really touch on fake news in his post, though Schrage said fake accounts like the ones that purchased ads often distribute deceptive material, such as false news, hoaxes, and misinformation.
Facebook agrees to disclose ads that ran in the U.S. in 2016 from accounts associated with a Russian entity known as the Internet Research Agency to United States Congressional investigators. Earlier, this information was provided to Special Counsel Robert Mueller.
