That law requires the President to report to Congress each year on the progress in the fight against drugs and to certify that certain countries are cooperating fully in the drug interdiction efforts. If not certified. such countries are subject to a cutoff of foreign aid. My amendment would permit a reduction in visas and a cutoff of air service and would require termination of Customs preclearance facilities for countries which are not certified in the future. My amendment is based on the language of S. 1379. which I introduced on June 17. 1987. Senator NUNN. the distinguished chairman of the Permanent Subcommittee on Investigations. was a cosponsor of this bill.
