2002 State of the Union Address
Bush spoke about the September 11 attacks of the previous year that killed thousands of people in New York City, Virginia, and Pennsylvania. The Islamist terrorist organization al-Qaeda carried out the attack with 19 hijackers that took over four commercial airline flights and crashed them into the World Trade Center's Twin Towers in New York City's Lower Manhattan, and into the Pentagon in Virginia's Arlington County.
Siraj Wahhaj
Wahhaj was one of 170 people identified by US Attorney Mary Jo White in 1995 as "unindicted persons who may be alleged as co-conspirators" in the 1993 World Trade Center bombing, but was never charged, and denies any involvement with the bombing. 
Wahhaj was a defence witness at the trial of the Blind Sheikh, Omar Abdel-Rahman, the former leader of the Egyptian terrorist organization, Gama'a al-Islamiyya.
