WATCH: Where the Border Wall Ends

Exclusive video—Millions crossed illegally

Last November, I was showing a colleague an area I had discovered after a Border Patrol agent informed me about where people were crossing illegally. It was in Campo, California.

Tens of thousands crossed here unlawfully because the wall ended.

The main border wall ends here

This is located in the middle of nowhere, in the mountains, and is very difficult to find.

Illegal aliens were guided by cartel coyotes along the railroad tracks in Mexico to this spot where the border wall ended

I had to go off-road in 4-wheel drive to find it.
