There are only two types of companies: those that have been hacked, and those that will be. Even that is merging into one category: those that have been hacked and will be again.

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.

In planning an attack, persons have various roles.

And so every one of us in the FBI, I don't care if it's a file clerk someplace or an agent there or a computer specialist, understands that our main mission is to protect the public from another September 11, another terrorist attack.

Leaking of classified material is a concern.

The 19 hijackers that came over here to commit the attack on Sept. 11, there were those that were at the bottom of the line. There were those who were the principal conspirators. There were those who were the pilot. Everybody has a role.

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.
