Authorities face mounting pressure to release Nashville school shooter's manifesto: 'Very perplexing'

Authorities are facing mounting pressure to unveil the Nashville school shooter's manifesto to shed light on the motive behind the brutal massacre that left six people, including three children, dead last month. 

The FBI has been accused of stalling its release after officials reportedly found 20 journals, five laptops and a suicide note among other things at the shooter's home. The suspect, Audrey Hale, identified as trans and was a former student at The Covenant School before she carried out the deadly shooting last month.

Sen. Bill Hagerty, R-Tenn., called it "perplexing" that officials have yet to release a motive or any of her writings nearly one month after the tragedy during "Fox & Friends" Monday.
