sharing with us the name of the hotel you stayed in last night?

- Um —

No.

- If you've messaged anybody this week,

would you share with us the names of the people

you've messaged?

- Senator, no,

I would probably not choose to do that publicly here.

- I think that may be what this is all about.

- In 2015, we heard the report that this developer

Aleksandr Kogan had sold data to Cambridge Analytica.

- Did you or senior leadership do an inquiry

to find out who at Facebook had this information

and did they not have a discussion about

whether or not the users should be informed

back in December of 2015?

- Senator, in retrospect,

I think we clearly view it as a mistake

that we didn't inform people.

And we did that based on false information

that we thought that the case was closed,

and that the data had been deleted.

- So there was a decision made on that basis

not to inform the users. Is that correct?

- That's my understanding, yes.

- I assume Facebook's been served with subpoenas

from the special counsel Mueller's office.

Is that correct?

- Yes.

Actually, let me clarify that.

I actually am not aware of a subpoena.

I believe that there may be.

But I know we're working with them.

- Thank you.

- If I buy a Ford and it doesn't work well

and I don't like it, I can buy a Chevy.

If I'm upset with Facebook,

what's the equivalent product that I can go sign up for?

- The average American uses eight different apps —

- Okay.

- — to communicate with their friends

and stay in touch with people —

- Okay.

- — ranging from text apps —

- — which is —

— to email.”

- Which is the same service you provide.

- Well, we provide a number of different services.

- Is Twitter the same as what you do?

- It overlaps with a portion of what we do.

- You don't think you have a monopoly?

- It certainly doesn't feel like that to me.

- Okay.

- Do you need to look behind shell corporations

in order to find out who is really

behind the content that's being posted?

And if you may need to look behind a shell corporation,

how will you go about doing that?

How will you get back to the true,

what lawyers would call 'beneficial owner'

of the site that is putting out the political material?

- So what we're going to do is require a valid government identity

and we're going to verify the location.

So we're going to do that,

so that way someone sitting in Russia, for example,

couldn't say that they're in America

and therefore able to run an election ad.

- But if they were running through a corporation domiciled

in Delaware, you wouldn't know that they were actually

a Russian owner.

- Senator, that's— that's correct.”
