A woman and two children drowned in the Rio Grande near Eagle Pass on Friday night as they were attempting to cross the U.S. southern border.
U.S. Customs and Border Protection told TPR that Border Patrol was prevented from deploying lifesaving efforts by agents with Operation Lone Star, the controversial Texas border security initiative.
Under the direction of Gov. Greg Abbott, Operation Lone Star this week seized control of Eagle Pass' Shelby Park, which faces the Rio Grande and has denied access to the Border Patrol.
The bodies of the migrant woman and two children were eventually recovered by Mexican authorities.
The Texas Military Department acknowledged in a statement to TPR that it was contacted by Border Patrol about a "migrant distress situation" at 9pm on Friday night and did not deny that it blocked access.
