Safeguarding Against Fabricated Exploitation Through Artificial Intelligence Act of 2026

Maddy summaryThis bill prohibits federal agencies from purchasing or using artificial intelligence models that fail to meet specific safety standards designed to prevent the creation of child sexual abuse material and non-consensual intimate images of adults. It requires the National Institute of Standards and Technology to establish performance benchmarks and a testing program within 180 days of enactment, while also mandating that agencies remove non-compliant software from their systems. The legislation includes a "cure" option allowing vendors to fix identified flaws at their own expense to avoid removal, and it bans the sale of tools specifically designed to bypass these safety controls. Additionally, the bill creates a private right of action, enabling individuals whose images are used to generate illegal content to sue developers for damages or injunctive relief.

National Workforce Transition Fund Act of 2026

Maddy summaryThis bill creates a temporary National Workforce Transition Fund to help workers and employers manage labor market changes caused by artificial intelligence and emerging technologies. The fund is financed by exempting AI data centers from certain tax depreciation limits, with the resulting revenue transferred to the Treasury and then allocated to the fund over five years. A new National Workforce Transition Board will oversee the program, developing strategies to assess workforce impacts and directing resources toward training, job placement, and employer retention initiatives. The legislation prioritizes support for workers facing employment disruption without requiring them to prove that technology was the sole cause of their job loss, while also funding improvements to labor market data systems. All provisions related to the fund and workforce activities are set to expire five years after the bill is enacted.

Data Center Tax Accountability and Disclosure Act of 2026

Maddy summaryThe Data Center Tax Accountability and Disclosure Act of 2026 modifies tax rules and establishes reporting requirements for large data centers. It removes a tax incentive known as bonus depreciation for artificial intelligence data centers unless they meet specific green building standards, such as LEED Platinum or Gold certification. Additionally, the bill requires operators of data centers consuming at least 25 megawatts of power to submit detailed annual reports on their water and electricity usage, emissions, and backup power systems to state or federal agencies. These reports must be made public, and the law prohibits companies from using confidentiality agreements to hide this information. Operators who fail to comply with these reporting requirements face daily civil penalties of up to $100,000 for intentional violations.

AI AGENT Act of 2026

Maddy summaryThe AI AGENT Act of 2026 establishes a legal framework allowing users to authorize third-party software agents, known as custodial user agents, to manage their online accounts and data on large platforms with over 50 million customers. To enable this, the bill requires these platforms to provide transparent, non-discriminatory access interfaces and mandates that the agents operate under strict duties to protect user privacy, prevent harm, and avoid using data for advertising or selling. The Federal Trade Commission is tasked with registering these agents, setting technical standards for secure data exchange, and enforcing compliance through a system that includes public reporting and penalties for unfair practices.

Julius Rosenwald and Rosenwald Schools National Historical Park Act

Maddy summaryThis bill would establish the Julius Rosenwald and Rosenwald Schools National Historical Park, a unit of the National Park System, to honor philanthropist Julius Rosenwald and the Rosenwald Schools that educated over 600,000 African American children in the segregated South from 1912 to 1932. The park would include three restored schools (in Maryland, South Carolina, and Virginia) and a visitor center in Chicago, Illinois, to preserve these sites and share their history through exhibits and educational programs. It also creates a national network to connect remaining Rosenwald Schools, enabling coordinated interpretation and resource-sharing across the country.

American Battlefield Protection Program Amendments Act of 2025

Maddy summaryThis bill reauthorizes and modifies the American Battlefield Protection Program through 2035, extending funding deadlines and increasing grant percentages for battlefield preservation. It raises the maximum federal share for battlefield acquisition, interpretation, and restoration grants from 50% to 75% and sets a $2 million annual appropriation for these programs. The bill also mandates new studies to identify, assess, and propose preservation options for sites tied to the French and Indian War (1754-1763) and Mexican-American War (1846-1848), requiring consultation with states, tribes, and preservation groups. The studies must be completed within two years and reported to Congress, focusing on site significance, threats, and potential preservation strategies.

To support the implementation of these reporting requirements, the bill appropriates $12 million for fiscal year 2026.
