DEL RIO, Texas — State troopers deployed to the border by Gov. Greg Abbott are being credited for doing the federal government’s job and stopping thousands more migrants in Mexico from illegally crossing into the United States after well over 15,000 made it through here late last week.

A swarm of Texas Department of Public Safety officers, known as troopers, descended on the riverbank Saturday afternoon as a show of force to deter people in Mexico from wading across the Rio Grande. Approximately 150 black SUVs were still lined up Sunday afternoon on the dirt road that runs parallel with the river.
