Department of Justice is working with federal agencies to look into allegations made by a Texas trooper in an email sent to his superiors, in which he described how he and his partner were ordered to push back migrants into the Rio Grande River and deny them water despite the searing heat. The email details a series of interactions the trooper had with migrants in Eagle Pass from June 24 to July 1 and provided insight into how the use of razor-wire traps and buoy barriers under Gov. Greg Abbott’s border security initiative known as Operation Lone Star has further endangered the lives of migrants.
