Assessments

The promise was to introduce and support the Build Nuclear with Local Materials Act, not to secure final enactment. Evidence shows Sen. Cynthia Lummis officially introduced the bill on May 15, 2026 and then materially supported it by chairing a May 20, 2026 EPW subcommittee hearing examining the measure. In a federal legislative context, those actions satisfy a promise framed around introduction and support of specific legislation.

Those actions satisfy the promised legislative effort within her current federal term.

Sen. Lummis formally introduced the Build Nuclear with Local Materials Act (press release dated May 15, 2026) and subsequently chaired/held a Senate EPW committee hearing to examine the bill (May 20, 2026). Those actions satisfy the claim to introduce and support the legislation to direct the NRC to pursue rulemaking on commercial-grade materials in non-safety structures. The bill has committee-level activity but not enactment; however, the promise specified introduction/support, which was met in the same term.
