DEL RIO, Texas - A federal judge will hear arguments Tuesday over whether U.S. Border Patrol agents can be compelled to testify in the upcoming criminal trial of former Uvalde CISD Police Chief Pete Arredondo.

Arredondo's defense team is seeking testimony from federal agents who responded to the Robb Elementary School shooting, arguing that their accounts are critical to preparing for his state criminal trial.

The hearing stems from a federal lawsuit filed by Arredondo after U.S. Customs and Border Protection declined to make certain agents available for testimony.
