 Let me ask you about anti-trust issues. In 2013, Facebook bought Onavo, which is a virtual private records network that claimed to protect users' privacy. In fact, Onavo's access to private information about its users provided Facebook with unparalleled ability to track potential competition. I want to know whether Facebook used data from Onavo when it decided to purchase WhatsApp in 2014. Senator, I believe that data from Onavo was one of the sources that the team looked at, but I don't think it would have taken using Onavo to understand that WhatsApp was a great product. I don't think that was determinative in my decision to pursue that. Well, in fact, the House Anti-Trust report says Onavo data was used to determine whether WhatsApp was, quote, killing Facebook Messenger, end quote. My time has almost expired, but let me just say finally that anti-trust action by the Federal Trade Commission is long overdue. I believe that decisive action is necessary, including very likely breaking up Facebook as a remedy. All options ought to be on the table, including the investment of Instagram and WhatsApp, the FTC autoimpose, strict conditions on how Facebook uses consumer data and competes with rivals, because the abuse of competition must end. Mr. Chairman, I asked that three letters from civil rights groups regarding disinformation aid speech on Twitter, Facebook, and YouTube, and also a letter from the Coalition of Children's Protection Advocates on the Urnit Act and Child Sexual Abuse Material on Digital Platform. Thank you both for being here today.
