Tulsa Public Schools security guard no longer at McLain after pushing girl against the wall

"He got in my ear and started yelling, and yelling and yelling and yelling," the 15-year-old student tells KTUL, "so I pushed his face away from me. Then afterwards he grabbed my shirt and hoodie and pushed me up against the wall and kept pushing and pushing and pushing, and he was trying to open up the door and then pushed me down on the floor."
