Combating Illicit Xylazine Act

Maddy summaryHR 1266, the Combating Illicit Xylazine Act, adds xylazine - a veterinary sedative increasingly found in illicit drug mixtures - to Schedule III of the Controlled Substances Act, regulating its use and trafficking. It directly affects veterinarians, animal owners, and manufacturers by allowing xylazine to be legally dispensed for animal use under specific veterinary prescriptions, while prohibiting non-veterinary human use. The bill includes transition periods (60 days for practitioners, 1 year for labeling) to ease compliance for manufacturers and practitioners, and requires the DEA and FDA to expedite necessary applications. It also mandates two congressional reports on xylazine's illicit use and trafficking patterns, and directs the Sentencing Commission to review penalties for offenses involving xylazine.

AM Radio for Every Vehicle Act of 2025

Maddy summaryThis bill requires all new passenger vehicles manufactured for sale in the U.S. to include AM radio as standard equipment (not an optional add-on) by 2027-2028, depending on manufacturer size. It mandates that AM radio receivers must be easily accessible to drivers and allows compliance through digital AM broadcast technology. During a transition period, manufacturers must clearly label vehicles without AM radio but cannot charge extra for this feature. The bill also mandates a GAO study on AM radio's role in emergency alerts and includes a 10-year sunset provision for the rule. It preempts state laws regarding AM radio access in vehicles.

Don Young Doug LaMalfa Indian Buffalo Management Act

Maddy summaryThis bill establishes a framework for the Department of the Interior to work with Indian Tribes and Tribal organizations to restore and manage buffalo populations on Indian lands. It authorizes the Secretary of the Interior to provide contracts, grants, and technical assistance to support tribal buffalo restoration programs, commercial buffalo activities, and mobile meat processing facilities. The legislation also requires ongoing consultation between the Department and tribes on buffalo management initiatives and ensures that culturally sensitive tribal information remains confidential. Additionally, the bill allows for the transfer of surplus buffalo from federal lands to Indian lands and explicitly preserves existing treaty rights of Indian Tribes, with all provisions set to expire seven years after enactment.

To amend the National Trails System Act to direct the Secretary of the Interior to conduct a study on the feasibility of designating the Bay Area Ridge National Scenic Trail, and for other purposes.

Maddy summaryHR 7254 requests a study to evaluate designating the Bay Area Ridge Trail as a National Scenic Trail. The bill directs the Secretary of the Interior to complete a feasibility study within one year, consulting with the Bay Area Ridge Trail Council and relevant agencies. The study would assess the 550-mile trail - currently 415 miles completed - connecting over 75 parks and open spaces across the San Francisco Bay Area. This bill does not designate the trail as a National Scenic Trail but initiates a review process to determine its potential for that status. The study would examine the trail’s scenic, historic, and recreational value, including its connections to urban areas and natural features like the Golden Gate Bridge and San Andreas Fault.

Providing for congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by U.S. Immigration and Customs Enforcement of the Department of Homeland Security relating to "Establishing a Fixed Time Period of Admission and an Extension of Stay Procedure for Nonimmigrant Academic Students, Exchange Visitors, and Representatives of Foreign Information Media".

Maddy summaryThis joint resolution seeks to overturn a Department of Homeland Security rule that would establish fixed time periods for admission and specific extension procedures for nonimmigrant academic students, exchange visitors, and representatives of foreign information media. If enacted, the bill would prevent this immigration regulation from taking effect, thereby maintaining the existing framework for how these individuals manage their stay in the United States. The measure directly affects international students, cultural exchange participants, and foreign journalists by blocking changes to their visa duration limits and renewal processes.

Doug LaMalfa Federal Disaster Tax Relief Certainty Act

Maddy summaryThis bill modifies tax rules to provide relief for individuals affected by major disasters. It allows taxpayers to deduct disaster-related losses (like damaged homes or personal property) more easily by creating a new "disaster loss deduction" that combines certain casualty losses and adjusts for income limits. It also excludes wildfire relief payments (such as compensation for lost wages or home damage not covered by insurance) from taxable income for people in federally declared wildfire areas, effective 2026 through 2030. These changes apply to losses incurred in taxable years starting after 2024, specifically for disasters declared between 2025 and 2027.

ROMA Act

Maddy summaryThe Rooting Out Mislabeled Agriculture Act directs the Department of Agriculture to create and maintain a database of isotopic signatures for processing tomatoes, modeled after an existing system used to detect cotton grown with forced labor in China. This scientific fingerprinting technique analyzes specific ratios of elements like hydrogen and carbon to identify the geographic origin of tomato products sold as paste or mixed into other foods. The bill requires the agency to conduct research on improving these testing methods and coordinate with U.S. Customs and Border Protection to apply the data during import inspections. Additionally, the Secretary of Agriculture must submit a report to Congress within two years detailing the database's establishment, research results, and recommendations for further action.
