Fox Nation host Tomi Lahren said a disturbing video that shows heavily armed men at the U.S.-Mexico border escorting a migrant mother and son into the U.S. highlights precisely "why we need a wall."

U.S. Border Patrol surveillance cameras caught the armed smugglers escort the migrant family at 10:00 p.m. Saturday near the town of Lukeville in the southwest corner of Arizona.

The video shows four to five men in full tactical gear and masks -- carrying long guns and AK-47 assault rifles – escort a Guatemalan woman and her eight-year-old child under a vehicle barrier. The armed escorts turned back across the border. The woman and child turned themselves into border agents, who responded to the incursion.

Border Patrol officials told Fox News this is an unusual event and expressed concern that it will become a more regular occurrence – possibly leading to violence.

On "Fox & Friends" Wednesday, Lahren noted that the area where the migrants crossed contains no pedestrian fence, and they were easily able to get around the vehicle barrier and enter the U.S.

"That is 100-percent why we need a wall. A vehicle barrier clearly does not cut it," Lahren said.

She added that the border crisis has been exacerbated by a lack of urgency from Democrats, who she argued are more than happy to import "future voters" for their party.

"The Democrats in this country are welcoming in them in. They're rolling out the red carpet, especially in states like mine," Lahren, a California resident, said.
