WATCH: Inside look at the dangerous cartel human smuggling tunnels still being used at border

Cartels continue using storm drain tunnels in El Paso to smuggle humans and narcotics despite increased border security. U.S. Customs and Border Protection (CBP) faces challenges patrolling the tunnels due to their complexity and hazardous conditions, though migrant numbers have dropped significantly under President Trump. Smugglers now charge $20,000–$30,000 per person and use social media to recruit guides.
