Colored wristbands seen on the arms of illegal migrants at our southern border may have a dark meaning that most outside of the cartels' influence don't know about.

In a Friday video, Texas Sen. Ted Cruz made a midnight visit to the Rio Grande to review the ongoing migrant crisis left virtually unchecked by President Joe Biden and his administration.

While watching border security desperately try to stem the tide of people illegally entering the U.S., Cruz made a horrifying find by the river.

"Down by the river, in just a few minutes, these are the wristbands I found," Cruz said while holding up a fistful of the tattered scraps.

"A white wristband, blue wristband, white, a pink and a yellow," Cruz counted out before coming to a horrifying find.

"Look at the yellow wristband," the senator continued, holding up a tiny band. "That obviously was around the arm of a child, a young child."

Cruz explained that the colors of the bands are used by the different cartels to determine which of their human cargo is fully paid up and which still owes a debt to the narco-terrorists.
