Thanks, everybody. We're out of time.
I just have one question for both witnesses. I've been doing a lot of media responses, just about Facebook, Cambridge Analytica and our joint investigation. We're actually going to go over to London and try to hear from Facebook, especially Mr. Zuckerberg.
My biggest concern is the timely response to pull down, let's say, a third party ad that's going to negatively impact a campaign. We all know that the last week in the campaign is crucial, and it can be affected by the littlest of ads.
In terms of a timely response to groups like Facebook and other social media platforms, what do you suggest we do with that to have a quick response that really mutes that immediately?
