A joint resolution terminating the national emergency declared with respect to energy.
Sponsor Timothy Kaine (D). Joined Sep 18, 2025. 8 cosponsors. S.J.Res. 71 on Congress.gov
Introduced
This joint resolution terminates the national emergency relating to energy declared by the President on January 20, 2025, in Executive Order 14156.
The executive order states that the supply of and infrastructure for energy in the United States is insufficient to meet the country's needs. It defines energy as crude oil, natural gas, lease condensates, natural gas liquids, refined petroleum products, uranium, coal, biofuels, geothermal heat, the kinetic movement of flowing water, and critical minerals.
The executive order directs the heads of executive departments and agencies to use available emergency and other authorities to take certain actions to address this topic, including approving development of domestic energy resources, expediting the completion of authorized energy infrastructure (particularly in the Northeast, West Coast, and Alaska), and pursuing the use of emergency permitting provisions under certain environmental regulations.
The executive order also directs the Department of Defense to conduct an assessment of its ability to acquire and transport energy resources (particularly in the Northeast and West Coast), and invokes emergency military construction authority to address any vulnerabilities identified in the assessment.

9/11 Responder and Survivor Health Funding Correction Act of 2025
This bill modifies the World Trade Center Health Program (WTCHP), including by updating the formula for determining the program’s annual funding amounts and authorizing mental health providers to provide certain evaluations under the program.
The WTCHP is a federal health care program (terminating in FY2090) providing responders and survivors with monitoring and treatment of certified medical conditions related to the terrorist attacks that occurred on September 11, 2001. Under current law, the program’s annual federal funding is determined based on the amount specifically appropriated in the previous fiscal year, adjusted for inflation.
The bill establishes a new federal funding formula for FY2026-FY2090 that is generally based on annual changes in the number of enrollees. The bill also increases the amounts the program may spend annually on medical research and activities relating to data collection. The bill requires the National Institute for Occupational Safety and Health (NIOSH), which administers the program, to submit a report to Congress on the program’s projected budgetary needs and expenditures.
In addition, the bill authorizes licensed mental health providers to perform initial health evaluations with respect to mental health conditions for purposes of determining eligibility under the WTCHP. NIOSH must issue regulations specifying the categories of mental health providers that may perform these activities.
