Four CDC workers, who were not authorized to speak publicly, told CBS News under the condition of anonymity that they were "deeply disappointed and frustrated" by an apparent lack of leadership following Friday's shooting​.

NEW YORK (Reuters) -Grappling with the aftermath of a shooting that killed a police officer and left nearly 100 shattered windows, leaders at the Centers for Disease Control and Prevention held virtual meetings with employees on Tuesday to rebuild trust at the agency's Atlanta headquarters.

CDC security guards stopped White from driving into the campus on Friday before he parked near a pharmacy across the street and opened fire from a sidewalk. The bullets pierced “blast-resistant” windows across the campus, pinning employees down during the barrage. More than 500 shell casings were recovered, the GBI said.
