Sudanese President Omar Hassan al-Bashir wrote a letter on April 15, 1997, “making an unconditional, no-strings-attached offer of counterterrorism assistance to Democratic Congressman Lee Hamilton of Indiana, who had long been an influential voice in foreign policy.” Multiple copies were sent to National Security Advisor Sandy Berger. In it, Al-Bashir “invited the FBI’s counterterrorism unit, and other official delegations, to visit Sudan and probe its intelligence files. There was no official response from the Clinton Administration.”
