The meetings come as Congress is investigating the role of Russian actors in the 2016 U.S. election, including thousands of advertisements that ran on Facebook. Sandberg said she supports publicly releasing the advertisements, as well as the pages they were linked to.
Leaders of a House Intelligence Committee panel said they plan to release the ads, likely after a Nov. 1 hearing, according to NBC News.
Sandberg said the targeting of those ads will also be released.
"We don't want this kind of foreign interference," Sandberg said. "These ads are divisive, and they are down, and the pages are down, because they are from fake accounts ... a lot of them, if they were run by legitimate people, we would let them run."
But Sandberg also called for other platforms, as well as the government, to rise to a similar standard of transparency. She noted that ads that promote violence and hate were part of the problem that Facebook had already been working to address.
Sandberg said that in the early days of monitoring on Facebook, preventing the hacking of private accounts was a primary goal.
"And then we started to hear the rumors — and this was around the election itself — of a different kind of attack," Sandberg said. "It was a more subtle [attack], even though just as important, which is posting in an inauthentic way to try to be deceptive and divisive."
She said that at this point, Facebook believes it has done a "thorough" job of identifying the Russian actor in question, thanks in part to the use of rubles to purchase the ads and the presence of fake accounts.
"We are following up aggressively on every lead we have," Sandberg said. "What we really owe the American people is determination. We are determined."
