create a million pills in this country. easy to get across normal ports of entry and mail. asked the acting drug czar about this issue, the wall and mail. >> when it comes to this issue about the wall and border security versus mail, is there one that worries you more? >> they're both important. so i mean i'll look at whole supply challenge. just doing a better job at tightening our security. we want to reduce the drug supply coming into the country. and right now fentanyl coming through in small packages in the mail is a huge threat. >> there's a million pieces of mail as you know every day coming in with really no electronic surveillance. don't know where it came from, how many countries visited beforehand and exactly what is in it. that's the big problem with fentanyl and opioid crisis.
