All field operations for the Border Patrol’s Del Rio Sector have been suspended “due to overcrowding at processing facilities, according to a source within U.S. Customs and Border Protection” reports Breitbart.

“The absence of agents performing their border security mission was noticeable as migrants crossed the Rio Grande and searched for authorities to surrender to on Sunday” the report adds.

Breitbart Texas posted “along several of the busiest crossings along the Rio Grande in Eagle Pass where migrants continued to surrender to Texas Department of Public Safety troopers and soldiers with the Texas Army National Guard.”

Breitbart reports on the information gathered while posted:

In one instance, three migrants forded the river and attempted to surrender to Breitbart Texas. The three Nicaraguan migrants were directed to state authorities more than one-half a mile from their crossing point.

Several other migrants crossed the Rio Grande on Sunday unabated by authorities. Immigration and police entities staged in Mexico attempted to stop several migrants from fording the river but were unsuccessful.

One migrant attempting the crossing struggled with the river’s strong currents but ultimately reached the United States safely. There were no law enforcement officers nearby to receive the migrant who later searched the banks for authorities where he could surrender.

The CBP source, who was not authorized to speak to the media, told Breitbart Texas “all agents received a radio broadcast early on Sunday removing them from the field. Management advised the agents to report to their respective stations to address the more than 2,500 migrant detainees awaiting processing and, in many cases, release them into the United States.”

At one non-government shelter in Eagle Pass, “multiple busloads of processed migrants were released by the Border Patrol throughout the morning.”

“Each bus carried approximately 50 migrants. The migrants lined up outside the shelter as employees performed intake duties. The migrants will travel to their final destination in the United States once the shelter staff coordinates transportation arrangements” adds Breitbart.

Until the overcrowding issue is resolved, “the agency will only respond to emergency distress calls involving migrants and to receive migrants that surrender to state and local law enforcement authorities.”
