It was known to the CIA in the mid 1990's, that two men Khalid al-Mihdhar and Nawaf al-Hazmi, were Al Qaeda operatives. The NSA had wiretapped Osama Bin Laden's satellite phone also during this period. What did they hear, and what did the CIA know? The Saudis also knew of an employee, Omar al-Bayoumi, from the Saudi Arabian Presidency of Civil Aviation since 1975, who met with Khalid al-Mihdhar and Nawaf al-Hazmi, yet the Saudi government claim to not have any connection to al-Bayoumi. The CIA and Saudi intelligence made a concentrated effort to not allow information be known to either the FBI or Department of State regarding both men who were inside the United States in 2000. The question is, why?
