A draft version of the National School Boards Association’s September 2021 letter to the Biden administration requesting federal intervention to investigate and potentially penalize “threats” leveled by protesting parents also asked that the Army National Guard and military police be deployed to certain school districts.

“We ask that the Army National Guard and its Military Police be deployed to certain school districts and related events where students and school personnel have been subjected to acts and threats of violence,” the draft read, according to the organization’s independent review of the incident released Friday.

The NSBA enlisted a law firm to do a deep-dive into the circumstances behind the letter, which the headquarters redacted many months ago after it led to nationwide backlash and a wave of state chapter exits. In a subsequent apology, the NSBA said there “was no justification for some of the language included in the letter. We should have had a better process in place to allow for consultation on a communication of this significance.”
