This source cluster combines current web verification, the repo's existing D20 and litigation material, the direct student-forum video, and official or mainstream reporting to place Bernadette Guthrie as a recurring D20 parent-advocacy actor rather than only the defendant in Wilburn v. Guthrie. The current repo supports a narrow but durable page for her school-board-election organizing, public-comment advocacy, DAC-linked bond scrutiny, library-policy testimony, and later conflict with Derrick Wilburn and the district.
The strongest present-tense external sources are the 2021 and 2022 KOAA reports, the 2024 Colorado General Assembly hearing summary, the 2024 CPR bond-process article, the accessible Gazette reporting and summaries around the Wilburn conflict, and the 2026COA13 appellate opinion. Inside the repo, the student-led 2023-10-13 D20 candidate-forum video is the key direct source for the event that later drives the Wilburn dispute, while the existing D20 and Wilburn summaries preserve already-ingested context. The resulting evidence base is strong for Guthrie's public advocacy footprint, but thin on broader biography outside that role.
