summary - 500+-page final report (released Dec. 2, 2024, formally submitted at a Dec. 4 markup) concluding a 2-year investigation: 100+ investigative letters, 30+ transcribed interviews/depositions, 25+ hearings, and (per the subcommittee) “more than one million pages of documents” reviewed, including subpoenaed EcoHealth Alliance/NIH/WIV-related communications. Concludes COVID-19 “most likely emerged from a laboratory in Wuhan,” citing the virus’s biological characteristics, WIV’s history of gain-of-function research the report characterizes as conducted at inadequate biosafety levels, EcoHealth’s alleged failure to report certain gain-of-function results to NIH as required, and reports that WIV researchers fell ill with a COVID-like illness in fall 2019. The investigation’s findings triggered HHS’s formal debarment of EcoHealth Alliance and Peter Daszak from federal funding.

relevance_note - The most comprehensive documentary record of subpoenaed EcoHealth/NIH/WIV communications assembled to date on the institutional side of the lab-leak case, but produced and framed entirely by one political party (see motivatedness) - weigh its subpoena-derived primary facts separately from its interpretive conclusion.
