JOHN BRENNAN:

Oh, I don't believe it's a fair criticism.

These situations, these types of assaults and attacks against the compounds frequently take place in a very dynamic environment. And I think it was no secret to anybody that the situation in Libya was rather tenuous. And so I think that the agency and the rest of the intelligence community had highlighted that, in terms of the strategic concerns and warnings that we had.

It's very difficult to get the tactical intelligence. But we always try to take lessons away from these types of incidents, particularly when there was tragic loss of life on the part of U.S. personnel and others that were there.

So, with each of these incidents, I think what we do is to make any type of adjustments that we believe are necessary in terms of our processes and procedures. But I'm very proud of what the agency officers heroically did that night in Benghazi, and it could have been much worse, except for the work that we and others did at that time.
