administration. >> all of this is the result of a whistleblower who released thousands of documents showing the inner workings of the social media empire. speaking to "60 minutes" saying the company puts profits over public safety, including the mental health of children and teenagers. cnn's chief media correspondent brian stelter joins me now. so let's start with this worldwide outage. the longest in facebook history. what is going on there, brian? >> facebook doesn't seem to know. or if they do know, they aren't revealing it to anybody. this has been going on more than 4 1/2 hours. all stopped scrolling. maybe it's a wake-up call for the hundreds of millions of users that rely on these platforms every day around the world. no reason to think it's related to this incredible whistleblower and the leaks coming out, but facebook is in damage control mode right now. having a harder time defending themselves because they can't even sblog their own email accounts. but many of the facebook whistleblower's claims they are saying are misleading. decide for yourself. here's what she said.
