Assessments
McCormick sponsored and introduced S.3269, the Liquid Cooling for AI Act of 2025, during his Senate term, and the bill text closely matches the promise by directing GAO and DOE reviews, recommendations, stakeholder input, and best-practice development for liquid cooling in AI data centers. However, the official bill status remains only introduced and referred to committee, with no evidence of passage, enactment, or implementation of the mandated studies or best-practice framework. This is a serious legislative attempt but not delivery of the promised policy outcome.
McCormick materially acted on the promise by sponsoring the Liquid Cooling for AI Act of 2025 on November 20, 2025, a bill that matches the claim's substance by calling for a GAO study, DOE evaluation and report, and development of best practices for liquid cooling in AI data centers. But as of June 14, 2026, Congress.gov shows the bill only at the introduced and committee-referred stage, with no enactment or further advancement. In federal office context, introducing and backing the legislation counts as meaningful progress and a serious attempt, but not full delivery because the promised legislative outcome has not been completed.
Senator David McCormick introduced and actively supported the Liquid Cooling for AI Act of 2025, which mandates federal studies, DOE evaluations, and best practices development for energy-efficient liquid cooling technology in AI data centers. However, evidence indicates the bill is still in committee and has not yet been enacted into law. Thus, there has been a significant legislative attempt directly aligned with the promise's content, but the ultimate outcome (enactment or full implementation) has not yet occurred.
Senator David McCormick introduced the Liquid Cooling for AI Act of 2025, specifically aimed at promoting energy-efficient liquid cooling technology in AI data centers, including mandates for federal studies, recommendations, and the development of best practices. Multiple sources confirm McCormick's sponsorship and active advancement of this targeted legislation, fulfilling the 'support and advance legislation' aspect of the promise. However, the legislation has only been introduced and is still in committee, and there is no evidence it has passed into law or resulted in implemented changes yet. Thus, the promise has been partially fulfilled, reflecting significant legislative effort but not final policy delivery.
