The suspected gunman who attacked the Centers for Disease Control and Prevention's campus on Friday may have fired many hundred rounds, law enforcement said on Tuesday.

The CDC director described the dangers of misinformation, four days after a gunman shot at the headquarters in Atlanta, claiming the COVID-19 shot sickened him.

Some public health care workers say the shooting that killed a police officer and rattled the CDC campus shouldn’t be surprising in the face of ongoing misinformation about immunizations.
