U.S. Secretly Met With Followers of Blind Sheik Omar Abdel Rahman Before Controversial Visa Application

Followers of Omar Abdel Rahman made overtures to U.S. diplomats one year before the radical sheikh entered the United States on a visa approved by a CIA agent.

During several meetings with diplomatic officers at the U.S. embassy in Cairo, members of al-Gama'a al-Islamiyya (The Islamic Group) provided extensive details about the operations of one of Egypt's most notorious terrorist organizations.

Initiated by al-Gama'a, the meetings were aimed at creating a dialogue with the U.S. in the hopes of eventual, unspecified cooperation. The initiative was based on a perception that the U.S. enjoyed similar cooperation with the Muslim Brotherhood in Egypt.

Less than four years after the approach, an al-Gama'a terror cell led personally by Abdel-Rahman bombed the World Trade Center in New York City.

It's taken from two embassy cables he obtained through FOIA requests. This is only a small tile in the mosaic, but it is really good work.
