Introduce and support a Congressional Review Act resolution to overturn CMS's WISeR pilot program, blocking the AI-driven prior authorization system from denying or delaying care for Traditional Medicare patients.
Occurrences
Evidence
Senator Maria Cantwell (D-WA) and Senator Patty Murray (D-WA) announced they co-introduced a Congressional Review Act (CRA) resolution, led by Senator Ron Wyden, to overturn the WISeR model. The release lists Cantwell as a co-introducer and describes immediate next steps (gathering signatures for a discharge petition to force a floor vote).
GAO Decision B-337994 (May 12, 2026) concluded the WISeR Model notice meets the Administrative Procedure Act definition of a rule and is therefore subject to the Congressional Review Act, meaning Congress may use CRA procedures to disapprove the WISeR notice.
Assessments
Sen. Cantwell co-introduced and publicly supported a Congressional Review Act resolution to overturn the WISeR model (press release May 20, 2026). Additionally, a GAO decision (May 12, 2026) found the WISeR notice is subject to CRA review, providing the legal basis and window for the CRA measure Cantwell joined. These facts show she carried out the promised action during her term and actively worked to advance it (gathering signatures for a discharge petition).
