Vet CENTERS for Mental Health Act of 2026

Maddy summaryThe Vet CENTERS for Mental Health Act of 2026 requires the Secretary of Veterans Affairs to ensure that every state meets a specific minimum number of mental health treatment centers within one year of enactment. For states in the contiguous United States, this minimum is calculated as the greater of one center per 30,000 square miles of land or one center per 55,000 veterans based on census data. Non-contiguous states and territories must maintain at least one center or match their existing count from January 1, 2020, whichever is higher. To achieve these targets, the Secretary may open new facilities using buildings provided by state, local, or tribal governments, and can establish outstations in place of full centers if multiple additional sites are needed in a single state.

Route 66 National Historic Trail Designation Act

Maddy summaryThis bill designates the Route 66 National Historic Trail, covering approximately 2,400 miles from Chicago, Illinois, to Santa Monica, California, along all historical alignments of U.S. Highway 66 (1926-1985). It directs the National Park Service to administer the trail while respecting its unique character, requiring tribal consultation for significant impacts on Native American tribes, and explicitly prohibiting land acquisition beyond 1/4 mile on either side of the trail. The bill clarifies it does not create buffer zones, disrupt energy infrastructure (including pipelines or renewable projects), or designate the trail as part of the National Park System, while affirming existing authority for easements and rights-of-way.

NO PROFIT Act

Maddy summaryThe NO PROFIT Act prohibits social media platforms from selling or providing paid, early access to posts made by federal government officials and their immediate family members. It also makes it illegal for any person to buy or sell securities, commodities, or prediction market contracts while possessing this non-public information before it is available to the general public. The bill targets a wide range of officials, including the President, members of Congress, executive branch employees, and judges, as well as their spouses and dependent children. Violations by social media platforms result in civil penalties equal to the revenue earned from the unauthorized early access, while individuals who trade on this information face enforcement actions by the Securities and Exchange Commission or the Commodity Futures Trading Commission.

Critically Endangered Animals Conservation Act of 2026

Maddy summaryThe Critically Endangered Animals Conservation Act of 2026 establishes a dedicated fund within the existing Multinational Species Conservation Fund to provide competitive grants for the protection of animal species classified as endangered or critically endangered by the International Union for Conservation of Nature. The Secretary of the Interior will manage this program, awarding financial assistance to foreign wildlife authorities and qualified organizations to support projects such as habitat restoration, illegal trade enforcement, and scientific research aimed at recovering wild populations outside the United States. To ensure accountability and effectiveness, grant recipients must submit periodic progress reports that are generally made available to the public, while specific restrictions prohibit the use of funds for captive breeding unless it is strictly necessary for releasing animals back into the wild. The legislation authorizes $5 million per year in appropriations from fiscal years 2027 through 2032 and requires the Secretary to report on the program's results to Congress every two years.

Lowering Energy Costs through Grid Modernization Act

Maddy summaryThe Lowering Energy Costs through Grid Modernization Act encourages utilities to upgrade power lines by replacing old conductors with more efficient ones that carry more electricity and generate less heat. To support these upgrades, the bill allows for faster federal environmental reviews and makes it easier to secure permits for projects that fit within existing land rights. Additionally, the legislation expands a federal tax credit to include these high-performance transmission upgrades, offering a higher credit rate for smaller projects or those meeting specific domestic content requirements.

No Passes for Polluters Act of 2026

Maddy summaryThe No Passes for Polluters Act of 2026 requires Congress to explicitly approve any exemptions from Clean Air Act regulations before the President or federal agencies can use them. Under this bill, the President must submit a detailed message to both houses of Congress explaining the reasons and facts behind any proposed exemption, which then triggers a special legislative process. To pass such an exemption, a joint resolution must be approved by a two-thirds vote in both the Senate and the House of Representatives, with limited debate and no amendments allowed. Additionally, the Comptroller General will review these proposals to ensure they have legal authority, and any unauthorized use of exemptions could lead to civil lawsuits. The legislation also mandates that the President reconsider certain executive branch emissions regulations every three years.
