Book‑prompted Health Disclosures

High‑visibility investigative books about sitting leaders can force or precede official medical disclosures and reframe public narratives (here: Biden’s cancer announcement days before the book on his decline). Books thus act as a late‑breaking accountability mechanism that interacts with campaign timing, donor communications, and institutional opacity. — If investigative books routinely precipitate official health disclosures, they become a predictable lever for transparency and political timing with consequences for election administration, disclosure norms, and how inner circles manage sensitive information.
