As the Daily Mail article mentioned, last week The Tennessee Star, a conservative outlet,
announced that they have obtained a trove of Audrey Hale's writings, supposedly 80 notebook pages shown across 40 images.
They've been drip-feeding the contents of the Tranifesto with many articles since then along with additional articles about how the Metro Nashville Police Department and the Vanderbilt University Medical Center are related to the shooting and its coverup. In particular, The Tennessee Star also published
a May 11, 2023 FBI memo discouraging the MNPD from publicly disseminating the "legacy tokens" of mass shooters (PDF attached below),
which the FBI reportedly refuses to confirm, and
a June 1, 2023 affidavit stating that Hale had been receiving psychological treatment from Vanderbilt Hospital since 2001 (PDF also attached below).
It appears that
Tom Pappert is the main reporter covering the Audrey Hale investigation. Here's a recent video of him being interviewed by his boss Michael Patrick Leahy about the silence of Vanderbilt Hospital (timestamp 47:59):
The A&N forum has
a thread about the reporting from The Tennessee Star.
Additionally, just this Wednesday, The Daily Wire (which is headquartered in Nashville)
obtained two of the notebook images comprising four pages and published them by way of Matt Walsh. He expresses his own analysis via
Twitter and
his show (for the first 20 minutes), but you can read the pages for yourself here:

Considering all the pages The Tennessee Star claims to have, we might soon see the Tranifesto more or less in full.
