BUMP Act

Maddy summaryThe BUMP Act (S 1374) bans devices that increase the firing rate of semiautomatic firearms to mimic machineguns, directly affecting owners of modified firearms. It prohibits importing, selling, or possessing devices (like "bump stocks") that speed up firing or eliminate the need for separate trigger pulls, and requires registration of existing modified semiautomatics within 120 days. The law exempts government agencies and pre-enactment modifications that are registered. This targets specific firearm modifications, not all semiautomatic weapons.

Tax Cut for Workers Act of 2025

Maddy summaryThis bill, the Tax Cut for Workers Act of 2025, expands the Earned Income Credit (EIC) to make it more accessible and generous for low-income workers without children. It lowers the minimum age for the credit from 25 to 19 (with exceptions for students, former foster youth, and homeless youth), removes the maximum age limit, and increases the credit amount and income thresholds. The bill also adjusts these amounts for inflation and allows taxpayers to use their prior year’s earned income if it was higher, applying to taxable years starting after 2025. These changes extend the credit to U.S. territories like Puerto Rico and American Samoa without prior time limits.

American Family Act

Maddy summaryThe American Family Act creates a new monthly child tax credit that would provide $300 per month for each child under age 6 and $300 per month for each child age 6 and older, with income-based eligibility limits. The credit would be refundable, meaning it could be paid even if a family owes no income tax, and would replace the current annual child tax credit. The bill establishes income thresholds ($150,000 for joint filers) above which the credit begins to phase out, with full phase-out at $400,000 for joint filers. It also includes provisions for "presumptive eligibility" to allow for advance payments based on previous tax returns or government program data. The bill would terminate the existing annual child tax credit after 2024, replacing it with this monthly payment system.

Content Origin Protection and Integrity from Edited and Deepfaked Media Act of 2025

Content Origin Protection and Integrity from Edited and Deepfaked Media Act of 2025 This bill requires certain tools used to create or modify digital content, including artificial intelligence (AI), to allow users to embed in such content information documenting its origin and history. This is known as content provenance information . The bill also prohibits the removal or alteration of content provenance information in certain circumstances. Specifically, tools used for the primary purpose of creating or significantly modifying content via algorithms, or creating or substantially modifying digital representations of copyrighted work, must allow users to include content provenance information in the resulting digital content. Further, the bill prohibits certain large websites and applications (e.g., social media applications) from removing, altering, tampering with, or disabling content provenance information; and it prohibits any individual or entity from taking such actions in furtherance of an unfair or deceptive act in commerce. Finally, the bill prohibits certain commercial uses of digital representations of copyrighted work that has associated content provenance information without the consent of the work’s owner. Specifically, such representations may not be used to (1) train a system that uses AI or an algorithm, or (2) create algorithmically generated or modified content. The bill provides for enforcement by the Federal Trade Commission and state attorneys general (or other authorized state officials). Owners of digital representations of copyrighted content with associated content provenance information may also bring suit to enforce violations related to their content.

Health Tech Investment Act

Maddy summaryS 1399, the Health Tech Investment Act, creates a new Medicare payment category for algorithm-based healthcare services (like AI tools used in diagnosis or treatment) starting January 1, 2026. It requires Medicare to pay based on manufacturer costs (including software, staff, and overhead) and protects these services in the special payment category for at least five years, preventing reassignment without sufficient claims data. This directly affects Medicare beneficiaries receiving these AI-driven services and healthcare technology companies developing them. The bill also codifies existing Medicare payment rules for software-as-a-service starting January 1, 2023.

A bill to amend the Safe Drinking Water Act to modify eligibility for the State response to contaminants program, and for other purposes.

Maddy summaryThis bill (S 1324) makes technical corrections to the Safe Drinking Water Act's eligibility rules for states seeking assistance under the State Response to Contaminants program. It clarifies who qualifies for federal grants, specifically allowing states to apply on behalf of: (1) disadvantaged communities meeting state affordability criteria, (2) small communities (under 10,000 people) lacking debt capacity, or (3) private drinking water well owners not connected to public systems. The changes streamline how states identify eligible communities and well owners for funding to address water contaminants. This is a procedural adjustment to existing program rules, not a new policy.

Public Service Freedom to Negotiate Act of 2025

Maddy summaryThe Public Service Freedom to Negotiate Act of 2025 establishes federal minimum standards for collective bargaining rights for public employees and supervisory employees. The Federal Labor Relations Authority will determine if states' laws "substantially provide" these rights, and if not, the federal standards will apply to affected workers. The bill guarantees rights like forming labor organizations, negotiating wages and working conditions, and resolving disputes through mediation or arbitration, while prohibiting strikes that would disrupt emergency services. Existing collective bargaining agreements and units are protected from the bill's implementation.

A resolution expressing the sense of the Senate that paraprofessionals and education support staff should have fair compensation, benefits, and working conditions.

Maddy summarySRES 158 is a non-binding Senate resolution expressing the chamber's view that paraprofessionals (like paraeducators) and education support staff (including clerical, custodial, and food service workers in schools) deserve fair treatment.

The resolution does not create new laws but urges federal and state action to address current gaps, including ending seasonal layoffs and ensuring access to benefits. It emphasizes these staff’s critical role in school environments while clarifying that it does not override existing collective bargaining agreements.
