The FBI begins to investigate Wadih El-Hage, who will soon work as bin Laden’s personal secretary. The FBI is investigating the February 1991 murder of Mustafa Shalabi (see (February 28, 1991)), the head of the Al-Kifah Refugee Center, a charity with ties to both bin Laden and the CIA. El-Hage, a US citizen living in Texas, came to New York to briefly run Al-Kifah so Shalabi could take a trip overseas, and happened to arrive the same day that Shalabi was murdered. Investigators find a message from El-Hage on Shalabi’s answer machine. They learn El-Hage had been connected to the 1990 murder of a liberal imam in Tucson, Arizona (see January 1990). [Miller, Stone, and Mitchell, 2002, pp. 148-149; Lance, 2006, pp. 67-68] Further, he visited El Sayyid Nosair, who assassinated Meir Kahane the year before (see November 5, 1990), in prison, and left his name in the visitor’s log. [Lance, 2003, pp. 50-51] However, the FBI decides there is not enough evidence to charge El-Hage with any crime. They lose track of him in early 1992, when he moves to Sudan and begins working there as bin Laden’s primary personal secretary. He will help bin Laden run many of his businesses, and will frequently take international trips on bin Laden’s behalf. [PBS Frontline, 4/1999; New York Times, 1/22/2000]
