A San Antonio doctor is defending the medical response to the Uvalde school shooting, following a critical media report. Dr. Ronald Stewart, senior trauma surgeon for University Health, says the responding medical team and Uvalde Memorial Hospital did the best they could. The report says two students and a teacher were pulled from a classroom alive but soon died. Stewart says they had suffered such critical wounds they couldn't have been saved. Helicopters carrying blood supplies were told to land at an airport three-miles away. Stewart says that's because the school was still an active shooting scene.
