The FBI's principal priority right now is protecting the United States against another terrorist attack.

There'll be differences of opinion in just about every intelligence analysis that you make.

So without getting into the specifics, I can tell you that to the extent that investigation is a relatively important investigation and meaningful, the president would have been periodically briefed.

It's because we need to determine who in this country is poised, positioned to commit terrorist acts.

I didn't know the organization, but the one thing you can say about the FBI, it's tremendously professional.

What we bring to the table is not only our 56 field offices in the United States and our number of resident agencies, but also we have 45 legal attaches overseas.

And from the moment that we realized it was a terrorist attack, there isn't an agent or a support person in the FBI that wasn't committed to bringing to justice those who were responsible for this.
