Leaking of classified material is a concern.

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

Prior to the passage of the Patriot Act, it was very difficult - often impossible - for us to share information with the Central Intelligence Agency, with NSA, with the other intelligence agencies, and likewise, for them to share information with us.

But since September 11, we have made every effort to try to work closely with state and local law enforcement.

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.

All I'm going to tell you is investigations, whether it be this and others, where you have partial facts, analysts, agents are always trying to interpret what those facts mean, extrapolate from them what they mean.

They're - FBI agents are some of the finest people you'll find anyplace in the country or the world. And I'm lucky to have the opportunity to work with them.
