WATCH: NBC News covers Loudon County Parents Outraged Over Sexual Assault

NBC News offered coverage of Loudon County parents outraged over a sexual assault that took place in a girl’s bathroom at one of the county’s school and what many consider a subsequent cover-up.

in June, Loudon Superintendent Scott Ziegler claimed “to my knowledge, we don’t have any record of assaults occurring in our restrooms”

Ziegler recently apologized, saying he misunderstood the question when he previously said there was no record of an assault.

An email shows Ziegler knew about the assault claim in May, weeks before his denial.
