>> that's a good question. i met with the chinese ambassador here. i have met with the chinese leadership there. i have raised it consistently. what they have said is two things. one, that they have made some of the precursors, in other words, the chemicals that go into making fentanyl illegal. they have in effect, scheduled them under the way we would do it here. and that they have begun, they say, secondly to crack down on some of these chemical companies producing it. but what they have done has not been effective. it continues to come in. our investigation indicated that if you send something by the postal service, from china, that it's guaranteed delivery. if you send it through one of the other carriers, say fedex or u.p.s. or dhl, a private care yes, it's not guaranteed. why? because after 9/11 we required all the private carriers to provided a advanced electronic data to law enforcement to be able to identify suspect packages and to be able to stop this stuff coming. in we didn't do it for the post office who said you ought to study it and come back to us with a report.
