This evening, my thoughts return to the first night I addressed you from this house. September 11, 2001. That morning, terrorists took nearly 3,000 lives in the worst attack on America since Pearl Harbor. I remember standing in the rubble of the World Trade Center three days later, surrounded by rescuers who had been working around the clock. I remember talking to brave souls who charged through smoke-filled corridors at the Pentagon and to husbands and wives whose loved ones became heroes aboard Flight 93. I remember Arlene Howard, who gave me her fallen son's police shield as a reminder of all that was lost. And I still carry his badge.
