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.

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.

American Franchise Act

Maddy summaryHR 5267, the American Franchise Act, clarifies when franchisors can be considered joint employers of franchisee employees under federal labor laws. It defines "substantial direct and immediate control" over essential employment terms like wages, benefits, hours, hiring, and discipline - requiring franchisors to actively set these terms to be deemed joint employers. The bill explicitly excludes routine brand standards, training, or minimal safety requirements from constituting such control. This directly affects franchisors and franchisees by limiting joint employer liability to cases where franchisors exert significant, ongoing influence over core employment decisions. The law applies prospectively to new cases after enactment, not past disputes.

To require the United States Postal Service to designate ZIP Codes for certain communities.

Maddy summaryThis bill requires the United States Postal Service to assign a single, unique ZIP Code to each of 80 specific communities across various states within one year of enactment. The legislation directly affects residents and businesses in these listed areas by ensuring they have their own distinct postal identifier rather than sharing codes with neighboring regions. The primary mechanism is a mandatory directive for the USPS to update its coding system to reflect these individual community boundaries.
