Facebook Chief Operating Officer Sheryl Sandberg said on Thursday that the company was fully committed to helping U.S. congressional investigators publicly release Russia-backed political ads that ran during the 2016 U.S. election.
“Things happened on our platform in this election that shouldn’t have happened,” Sandberg said during an interview in Washington with the Axios news website. “We told Congress and the intelligence committees that when they are ready to release the ads, we are ready to help them.”
The live interview was the first by a senior Facebook executive since the social media giant last month told congressional panels investigating allegations of Russian meddling during the election that it had found 3,000 politically divisive ads believed to have been bought by Russia.
Facebook found the ads on its network and said they had appeared in the months preceding and following the election on Nov. 8.
Sandberg said the company began hearing rumors of Russian attempts to use the platform to spread propaganda around election day, but did not give a precise timeline about when the company began its review.
Information about how the ads were targeted toward specific kinds of users would also be released, she said.
Asked if Facebook (fb) contributed to Democratic candidate Hillary Clinton’s defeat last year, Sandberg, an open Clinton supporter during the campaign, did not answer directly, but said it was important the website was “free from abuse” during any election in any country.
But Sandberg acknowledged the company had erred in how it handled the issue of foreign interference last year.
“It’s not just that we apologize. We’re angry, we’re upset. But what we really owe the American people is determination” to do a better job of preventing foreign meddling,” she said.
“We don’t want this kind of foreign interference” on Facebook, Sandberg added. “Any time there is abuse on our platform, it troubles us. It troubles us deeply.”
She said the company had been too permissive at times in terms of how advertisers are allowed to target users, and that Facebook did not want to allow ads that may be “discriminatory.”
Still, Sandberg said it was important to protect “free expression” on the world’s largest social network. If the Russian ads had been bought by legitimate accounts instead of fraudulent ones, many of them would have been allowed to run on the site, she said.
Sandberg said the company wanted other internet firms to work to make ad purchases more transparent, but said the company was still talking about the issue with lawmakers who want to introduce legislation on the topic.
