Meanwhile, on the Russian ad issue, Sandberg said the election meddling on the Facebook platform "shouldn't have happened" and she wouldn't discuss Russia or Trump.
Facebook has turned over the ads - and information on how they were targeted, such as by geography or to people with a certain political affiliation - to congressional investigators.
Also Thursday, a data mining and analysis company that worked on President Donald Trump's campaign confirmed it is turning over information to the House intelligence committee, to "provide it with information that might help its investigation".
While Facebook's chief operating officer, Sheryl Sandberg, now favours the release, she didn't say on Thursday when the company would do so.
"We know we have a responsibility to prevent everything we can from this happening on our platforms. and so we told Congress and the Intelligence committees that when they are ready to release the ads, we are ready to help them", she said.
Schiff said Sandberg wanted to convey that the company is serious about the issue to members of Congress, some of whom have expressed concerns that the company was reluctant to share information and ensure that foreign governments don't wage information campaigns in US elections.
A member of Congress who viewed about 70 of the roughly 3,000 ads said that they were meant to stir up strong emotions on all sides.
Mike Allen, Axios co-founder and interview host, asked Sandberg if she believed Twitter made a mistake by taking down Blackburn's advertisement. But when we say that, we're not saying we don't have a responsibility.
"When you allow free expression, you allow free expression", She said. Trump has denied that there was any collusion between his campaign and associates and Russian Federation. Facebook, she said, does owe America an apology. She said the company is also using "machine learning and automation" to target fake accounts that spread fake news.
Sandberg noted that this was an interesting conversation to be having this week considering Rep. Marsha Blackburn's (R., Tenn.) Senate campaign announcement ad was taken down from Twitter because of an "inflammatory" pro-life statement.
"We do not want this kind of foreign interference in Facebook", she added. Twitter later reversed its decision. "But the question is, 'Should divisive political or issue ads run?' Our answer is yes because when you cut off speech for one person you cut off speech for all people", she said.
"We don't allow hate, we don't allow violence, we don't allow bullying, and we work hard to get that stuff down", Sandberg said regarding the content allowed in Facebook advertising and content. "In that ad, there's a lot of positions that people don't like, that I don't like". Representatives from Facebook, Google and Twitter are expected to testify about Russian influence at hearings before the Senate and House intelligence committees on November 1.
