Heavily redacted version of 62-HQ-83894 long available on the FBI Vault; basis for the 'newly declassified' overstatement on the 2026 node.
A partial, heavily redacted version of 62-HQ-83894 circulated for years on the FBI's online reading room (the Vault). The 2026 PURSUE version is materially more complete. This prior release is the key fact that makes 'newly declassified' an overstatement: the 2026 action is largely a less-redacted re-release, with only a minority of genuinely new pages.
