Assessments

Public state: pending As of 2026-09-16 · verified · . Original AI recommendation (not independently established): unresolved. unknown A for effort

Lee materially supported termination by introducing H.R. 10143, whose text would terminate the Yucca Mountain licensing proceeding upon enactment. However, verified evidence says the adjudicatory hearing remains suspended and related litigation remains pending, so the licensing proceeding has not been shown terminated as of 2026-09-16. Introduction of the bill documents effort, not enacted delivery or a partial outcome.
