Shaffer Security Group (@ShafferGroup) — X Posts
@ShafferGroup is the corporate X account of Shaffer Security Group (SSG), founded by Greg Shaffer, described in reporting as a former FBI agent. It is not a citizen investigator — it is a first-party participant whose since-deleted posts are preserved as evidence of the dispute over which firm held the TPUSA security contract on September 10, 2025.

- September 26, 2025, 11:33 PM (deleted within hours, 13 views at capture) — posted that the security firm contracted by TPUSA when Charlie Kirk was killed "want[s] to remain in the shadows while my firm takes blame," stating "SSG was not and had not been affiliated or contracted to do security for TPUSA since 2022," with the Texas business record for Rockhouse Integrity Group LLC attached. (Capture)
- September 27, 2025 — a second post: "My firm was NOT in Utah on 9/10/2025... The private security firm, hiding in the shadows, not taking responsibility for their actions is Rockhouse Integrity Group, dba: Integrity Security Solutions." The attached record lists Brian Harpole as registered agent and manager. (Capture)
- The corporate registration core is a public record and independently checkable; the characterization of the other firm is one party's view in what reporting describes as a longstanding business dispute between former colleagues. Greg Shaffer repeated the substance to Headline USA.
- The account's April 2017 join date was separately captured to authenticate the deleted posts. (Capture)
Investigative value
The deleted posts are the clearest first-party statement on which firm was actually responsible for Kirk's private security at UVU — a question central to the security-failure record. That the posts were deleted within hours is itself part of the record. No wrongdoing by Brian Harpole, Integrity Security Solutions, SSG, or anyone else named is established by these documents.
