Facebook Inc. Chief Operating Officer Sheryl Sandberg said on Thursday 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.
