“Citing security concerns, U.S. Secretary of State Warren Christopher had ordered all American personnel to leave the embassy in Khartoum [Sudan] in February [7] 1996. Later, the CIA would have to ‘withdraw’ more than one hundred of its reports on Sudan when its main source–a rebel sympathizer earning $100 per report–failed a routine polygraph test. The ‘threats’ to the U.S. embassy were partly based on these later-discredited reports.”
