World War II Women's Memorial Location Act

Maddy summaryThis bill authorizes the placement of a memorial honoring women who supported the U.S. war effort during World War II (including those working as pilots, engineers, and in factories) on federal land in Washington, D.C. It specifies two locations: Area I on the National Mall map or the National Mall Reserve, as defined in existing law. The memorial was previously authorized by Section 702 of the 2023 Consolidated Appropriations Act (Public Law 117-328), and this bill clarifies its permitted locations.

Military in Law Enforcement Accountability Act

Maddy summaryThe Military in Law Enforcement Accountability Act requires the President to submit detailed justification to Congress before the military provides support to civilian law enforcement, including specific budget, timeline, and funding details, with a 30-day limit on such support unless Congress approves a longer period through a specific joint resolution process. It prohibits Department of Defense personnel (including military members) from holding civilian law enforcement positions concurrently, with limited exceptions for reserve members who must recuse during active duty. The bill also removes the military's authorization to deploy for "civil disturbances" without the new approval process and establishes a private right for individuals or governments to sue the federal government for violations. This directly affects the Department of Defense, military support to local police agencies, and DoD personnel's dual employment policies.

Dignity for Detained Immigrants Act

Maddy summaryThe Dignity for Detained Immigrants Act establishes minimum standards for detention facilities operated by the Department of Homeland Security, requiring them to follow the American Bar Association's Civil Immigration Detention Standards. It mandates annual unannounced inspections by the DHS Inspector General, with penalties including fines for noncompliant private facilities and transfers of detainees from noncompliant facilities. The bill requires DHS to publicly report on facility compliance, phase out private detention facilities over three years, and prohibit solitary confinement. It also ensures detainees have access to legal orientation, counsel, and more frequent custody review hearings. The bill directly affects all individuals detained in DHS custody, including immigrants, asylum seekers, and refugees held in facilities operated by or contracted to DHS.

FERC Greenhouse Gas and Environmental Justice Policy Act of 2025

Maddy summaryThis bill requires the Federal Energy Regulatory Commission (FERC) to consider environmental justice and greenhouse gas emissions when reviewing applications for natural gas pipeline projects and other infrastructure needing a certificate of public convenience and necessity. FERC must evaluate how projects affect communities disproportionately burdened by pollution (defined as communities of color, indigenous groups, or low-income areas) and quantify all foreseeable greenhouse gas emissions, including upstream leaks and downstream combustion. Projects emitting 100,000+ metric tons of CO2 equivalent annually are presumed to have significant climate impacts. Applicants must submit mitigation plans to address environmental effects, and FERC must attach enforceable conditions to certificates if mitigation is practicable - or provide a detailed explanation if it isn’t.

Developing and Empowering our Aspiring Leaders Act of 2025

Maddy summaryThis bill requires the Securities and Exchange Commission (SEC) to revise two specific regulations within 180 days of enactment. It would change the definition of "qualifying investments" for venture capital funds to include equity securities from qualifying companies (purchased directly or in secondary markets) and allow investments in other venture capital funds to count toward qualification. These revisions would directly affect venture capital funds seeking to maintain their regulatory status by altering the types of investments they can hold. The changes aim to adjust how venture capital funds structure their portfolios under current SEC rules.

Mikaela Naylon Give Kids a Chance Act

Give Kids a Chance Act of 2025 This bill expands the Food and Drug Administration’s (FDA’s) authority with respect to research on rare pediatric diseases, including by permitting the FDA to take enforcement action against drug sponsors that fail to satisfy pediatric study requirements and by reauthorizing programs that support pediatric research.  Specifically, the bill modifies requirements relating to molecularly targeted pediatric cancer investigations to permit research on new drugs in combination with active ingredients that have already been approved, provided certain conditions are met; permits the FDA to take enforcement action against drug sponsors that fail to comply with pediatric study requirements, if such sponsors demonstrated a lack of due diligence in satisfying the requirement; renews the FDA’s authority to award priority review vouchers to sponsors of new products intended to treat rare pediatric diseases through September 30, 2029; and reauthorizes through FY2027 certain funding for the National Institutes of Health to support priority pediatric research.  The bill also provides statutory authority for the FDA’s interpretation of the orphan drug exclusivity period. The bill specifies, consistent with FDA regulations, that the seven-year market exclusivity period for drugs for rare diseases or conditions (i.e., orphan drugs) prohibits the approval of the same drug for the same approved use or indication with respect to the disease or condition. (In Catalyst Pharmaceuticals, Inc. v. Becerra , a court rejected the FDA’s interpretation and held that orphan drug exclusivity extends to all uses or indications for the disease or condition.)

Low-Income Household Water Assistance Program Establishment Act

Maddy summaryThis bill establishes a federal program to help low-income households pay for drinking water and wastewater services. It provides $500 million annually (2026-2030) in grants to states and tribes that already administer energy assistance programs, allowing them to cover past-due bills or other costs for households meeting specific income criteria (e.g., receiving certain federal benefits or earning ≤150% of the poverty level). The program prohibits using these funds to replace existing assistance and requires technical help to streamline eligibility. It directly affects low-income households in participating states and tribes, particularly those facing water affordability challenges.

FRESHER Act of 2025

Maddy summaryThe FRESHER Act of 2025 requires the Secretary of the Interior to study stormwater runoff impacts from oil, gas, and mining operations on groundwater and aquifers. It mandates a specific analysis of measurable contamination, groundwater resources, and aquifer susceptibility to contamination in affected areas. The study must be completed within one year of the bill's enactment, with results reported to Congress. This bill directly affects oil, gas, and mining operations by establishing new federal study requirements for their stormwater runoff.

Electricity Transmission Scorecard Act

Maddy summaryThe Electricity Transmission Scorecard Act (HR 6176) requires electricity transmission owners and regional grid operators to publicly report on their performance using standardized metrics. It mandates biannual reports from transmission owners (TIAPS) and annual reports from regional grid operators (RIAPS) covering affordability, investment effectiveness, system reliability, interconnection fairness, and other key performance indicators. The bill establishes a framework for transparent, comparable data that would be publicly accessible through a government portal, allowing ratepayers and stakeholders to evaluate transmission service quality. This applies to all entities operating transmission facilities, including those not previously subject to FERC reporting requirements, aiming to improve transparency and accountability in electricity transmission.

Medical Nutrition Therapy Act of 2025

Maddy summaryThis bill would expand Medicare Part B coverage to include medical nutrition therapy for beneficiaries with a wider range of chronic conditions beyond current limits (diabetes and kidney disease). It specifically adds conditions like obesity, hypertension, eating disorders, cancer, gastrointestinal diseases, and HIV to the list of covered illnesses, allowing coverage for prevention, management, or treatment. The bill also allows more healthcare providers - including dietitians, nurse practitioners, and clinical psychologists - to deliver these services. This change would directly affect millions of Medicare beneficiaries managing these conditions who previously lacked coverage for medically necessary nutrition therapy.
