Two related pediatric health organizations have joined two Shelby County families in their lawsuit against Tennessee Gov. Bill Lee regarding his order allowing families to opt children out of school mask mandates.

The American Academy of Pediatrics (AAP) and the Tennessee chapter of the AAP joined the families, who were granted a temporary restraining order Sept. 3. The temporary restraining order stops Lee’s order in Shelby County, meaning families cannot opt out of the mandate, through Friday.
