I want to follow up on an area that Senator Levin was touching on.

If the privacy board met the constitutional standards, what you're telling me is you would not rule out giving them a subpoena.

My concern is, and I'll wrap up with this Mr. Chairman, that the pre-9/11 set of walls has been replaced with a new set of walls preventing information sharing.

I hope that Thursday's session can be done in public.

Why not require a judge to approve these National Security Letters?

What I am interested in knowing is, what is necessary at this point, Director Mueller, to initiate an investigation within the FBI?

Is it fair to say then, Director, that this staged development of information, as you describe it, is in fact the new standard of proof for issuing a FISA warrant and a National Security Letter?

I think that's a pretty sweeping comment that there really isn't any standard of proof, that there isn't any, to your terminology, no particular standard of proof.

With all due respect, Mr. Director, as I've said, you've worked very well with me. This is not what we've done over the years.

Are you aware of Doe v. Ashcroft?

I want to know more about this.

We ought to be fighting terrorism ferociously without gutting civil liberties.

I'm not aware of abuses.

But what is the standard of proof, then?

I'm concerned that a lot of these recipients aren't given notice of their right to challenge search orders.

Well, again, what is hard for us to address here is that we're to some extent doing oversight in the dark.

I would like to work with both of you and see if we can flesh out a bipartisan change there that would strike the right balance between security and individual rights.

How long, gentlemen, will it take for these Governors and cities to get the approval to bring the vaccines into the United States that they want?
