Evidence

On May 13, 2026 Senator John Cornyn announced he will introduce the "WATER for Farmers Act," which would impose tariffs on Mexico if it continues to violate the 1944 Water Treaty and fail to send owed water to the United States.

Cornyn publicly introduced targeted legislation (tariff-based penalties) to compel Mexican compliance with the 1944 Rio Grande water-delivery obligations, demonstrating concrete legislative effort to force Mexico to meet deliveries for South Texas.

The U.S. and Mexico reached an agreement under which Mexico will send at least 350,000 acre-feet of water per year during the current five-year cycle, committing to a minimum annual delivery amount to the United States.

Official bilateral agreement (reported by AP) changed practice toward a guaranteed minimum annual delivery from Mexico — a partial achievement on the underlying issue Cornyn has worked on, but implementation and consistency remain subject to follow-up and monitoring.

Assessments

partial same_term A for effort

Evidence shows Senator Cornyn both publicly advanced concrete legislative measures (the May 13, 2026 "WATER for Farmers Act" proposing tariffs on Mexico for treaty violations) and coincidentally the U.S. and Mexico reached a bilateral agreement (Feb 2026) committing Mexico to a minimum annual delivery. These actions demonstrate the candidate worked to force compliance and contributed material effort; however, the outcome is not a clear, fully independent delivery solely attributable to Cornyn (the bilateral agreement involved diplomatic negotiation and implementation/monitoring remains uncertain). Therefore partial credit is appropriate, with timing in the same term and an effort badge for a serious legislative attempt.
