Giuliani was in his final days as New York mayor when two planes crashed into the World Trade Center's twin towers on Sept. 11, 2001. He quickly became a national hero; within hours of the attack, the mayor, caked in dust, was visiting ground zero and walking through the chaos -- a scene shown repeatedly on television. He was dubbed "America's Mayor" by Oprah Winfrey and was named Time magazine's Person of the Year for 2001.
