Excerpts from Trump Cabinet Meeting June 21, 2018:

So we’ve created, and they’ve created, and they’ve let it happen — a massive child-smuggling industry. That’s exactly what it’s become. Traffickers — if you think about this — human traffickers are making a fortune. It’s a disgrace.

These alien minors were separated and sent all the way up here alone. But they really came up with coyotes. You know what a coyote is. Not good. These are not good people. They were sent up here with human traffickers because the Democrat-supported policies have allowed this to happen.

They [Mexico] encourage people, frankly, to walk through Mexico and go into the United States because they’re drug traffickers, they’re human traffickers, they’re coyotes.
