Cicilline to Zuckerberg: Facebook too big to contain deadly content

What he's saying: “Your platform is so big, even with the right policies in place, you can’t contain deadly content," the Rhode Island Democrat said. "Frankly, I believe it strikes at the very heart of American democracy."

• Cicilline pointed out that inflammatory and false articles often get a lot of engagement on Facebook. Keeping people on the Facebook platform is a key business strategy of the company and helps it serve more ads.

The other side: Zuckerberg responded that Facebook has a responsibility to limit the spread of harmful content and that there's no incentive for the platform to house that kind of content.
