Independently verified against the primary source. The Permanent Subcommittee on Investigations (PSI) landing page confirms Ron Johnson (R-WI) is the Chair. The PSI hearings page lists at least five hearings convened in 2025-2026 that directly investigate federal health agencies over the COVID-19 response, and all three hearings the prior rating cited were confirmed by exact title and date: 'The Corruption of Science and Federal Health Agencies: How Health Officials Downplayed and Hid Myocarditis and Other Adverse Events Associated with the COVID-19 Vaccines' (05/21/2025), 'Voices of the Vaccine Injured' (07/15/2025), and 'Unmasked: How Biden Health Officials Purposely Turned a Blind Eye Toward COVID-19 Vaccine Safety Signals' (04/29/2026). Two additional matching hearings also appear ('How the Corruption of Science has Impacted Public Perception and Policies Regarding Vaccines' 09/09/2025, and 'Plausible Mechanisms of COVID-19 Injections Causing Cancer...' 06/03/2026). As chair, Johnson personally set the subcommittee's agenda around this promise and drove a sustained series of investigations, which is well beyond a single supporting vote, so CHAMPIONED (+0.75) is the correct label rather than ATTEMPTED. It is not FULL because 'bringing accountability and transparency back' is an ongoing outcome, not a single completed deliverable. Applying the same standard to either party: a chair who convenes five topical hearings on the exact subject they promised to investigate is leading the effort. Confidence held at 0.85; the sources are live, primary, and directly on point.
