We need to make a greater investment in human intelligence.

I had earlier concluded that a war with Iraq would be a distraction from the successful and expeditious completion of our aims in Afghanistan. Now I had come to question whether the White House was telling the truth.

I have had national security background, 10 years on the Intelligence Committee, the last two years as chair.

This president has been reluctant to hold anybody accountable. No one was held accountable after September the 11th. Nobody's been held accountable after the clear flaws in intelligence leading up to the war in Iraq.

We need to have a strong defense focused on areas that are in the greatest vulnerability. I have been very concerned about America's 361 seaports as a point in which terrorist activities and materials could be brought into the country.
