That includes Cruz (R-Texas), who reeled off a number of conservative groups whose Facebook pages had been shut down.

ANNA ESHOO: Was your data included in the data sold to the malicious third parties - your personal data? Graham pointed out that if he wasn't happy with a specific model of a car, he had many other car options, but where does one go if they aren't happy with FB?

Zuckerberg demurred that he didn't know what a shadow profile is, and to be fair, it's not a term Facebook uses, at least publicly. Web developers can control what data is collected and when it is transmitted.

Zuckerberg began his hearing with the senators by indicating he was not excited to be there. Would an ad-free, paid version of Facebook work, anyway?

"If I'm upset with Facebook, what's the equivalent product that I can sign up for?"

Grabbing those photos from Harvard's "facebooks" - the school's database of students' pictures and basic information - on a protected computer network, landed Zuckerberg on probation by the university's disciplinary board after outrage from students prompted the site's shuttering. We need to know when someone is trying to repeatedly access our services.

"The GDPR requires us to do a few more things and we are going to extend that to the world", he said.
