Hey, what's up? It's Gustavo Arellano, and today we head back to the border, this time in South Texas.

My colleague, Molly Hennessy Fisk, takes it from here.

You brought your ID with you, correct?

Yes, okay, cool, because you'll need that to get back across the border.

So we're going to take you into Mexico and we're going to interview cartel and coyotes.

I'm totally joking. You know, I'm up for anything.

I felt the oxygen go out. Yeah. Oh, gosh.

So this is Samuel Hall. He's the founder of a militia called Patriots for America.

I followed Sam and the militia a few weeks ago.

We were at the U.S.-Mexico border, right next to the Rio Grande River, where the cities of

Eagle Pass, Texas and Piedras Negra's Mexico meet.

Yes, ma'am. We're right in Eagle Pass.

Eagle Pass is a rural area, mostly populated by ranchers.

It's sandy here along the banks of the river.

Sam calls the silt border glitter because it gets on everything.

who pass through after crossing the river illegally.

There's a lot of clothing and, like, detritus of shoes and...

This is just all...

This is Biden outerwear.

Biden outerwear.

Yeah. Is this stuff even fresh, though?
