In committee · Delaware Senate · Co-sponsor
A resolution condemning any acceptance of Presidential aircraft, or any other substantial gift, from a foreign government.

Maddy summarySRES 218 is a non-binding Senate resolution condemning the acceptance of presidential aircraft or other substantial gifts from foreign governments. It states such acceptance poses national security risks (citing Air Force One’s sensitive technology) and violates the Constitution’s Foreign Emoluments Clause, which requires congressional consent for presidential gifts from foreign states. The resolution demands that any such gift must have explicit congressional approval and urges rejecting foreign aircraft that don’t meet U.S. defense security standards. It applies to the President and sets a procedural expectation, not a new law, emphasizing constitutional compliance and public trust.

A resolution calling for the urgent delivery of humanitarian aid to address the needs of civilians in Gaza.

Maddy summaryThis resolution (SRES 224) calls for urgent U.S. diplomatic action to address the severe humanitarian crisis in Gaza, where approximately 2.2 million civilians face acute hunger and malnutrition, including 10,000 children identified with acute malnutrition since January 2025. It highlights that Gaza’s borders have been blocked since March 2, 2025, preventing entry of food, medicine, and other lifesaving aid, leading to closed bakeries and exhausted food rations. The Senate resolution specifically urges the White House and State Department to use all available diplomatic tools to end the blockade, secure hostage releases, and achieve a durable conflict resolution. As a non-binding resolution, it does not enact law but formally expresses the Senate’s concern and directs executive branch action.

Neighborhood Homes Investment Act

Maddy summaryThe Neighborhood Homes Investment Act creates a new tax credit to increase affordable homeownership in distressed communities by closing financing gaps. It allows developers to claim a credit equal to the difference between development costs and affordable sale prices, capped at 40% of development costs or 32% of the national median home price. To qualify, homes must be sold to individuals with incomes at or below 140% of area median income in designated distressed census tracts, with specific requirements for rehabilitation and affordability. The credit is designed to address housing shortages in low-income areas while requiring repayment if homes are resold within five years.

American Innovation and Jobs Act

Maddy summaryThis bill allows businesses to immediately deduct research and development (R&D) costs instead of spreading them over 60 months, directly benefiting companies investing in innovation. It increases the refundable R&D credit cap for small businesses from $250,000 to $750,000 over time, with specific phase-in amounts starting in 2025. Additionally, it expands access for startups by raising the gross receipts threshold for eligibility from $5 million to $15 million and increasing credit rates for qualified small businesses. These changes aim to make R&D tax incentives more accessible and valuable for smaller companies and new ventures.

Protecting Access to Ground Ambulance Medical Services Act of 2025

Maddy summaryThis bill delays Medicare payment changes for ground ambulance services until 2028 and adds temporary rate increases during a transition period. It directly affects Medicare beneficiaries using ambulance services and ambulance providers who bill Medicare, particularly in rural areas. Key provisions extend the effective date for payment adjustments from October 2025 to January 2028 and establish temporary payment rates: 26.7% for super-rural ambulance services and 4.3% or 3.4% for regular ground ambulance services during the transition period (October 2025-January 2028). These changes aim to prevent sudden payment cuts that could disrupt access to ambulance care.

ACCESS Act of 2025

Maddy summaryThe ACCESS Act of 2025 requires major social media and messaging platforms (defined as services with over 100 million U.S. users that monetize user data) to enable users to easily transfer their data to competing services and ensure their platforms can interoperate with rival services. It mandates that large platforms provide secure, machine-readable data portability and maintain transparent interfaces for competitors to connect with users. The law also establishes rules for third-party agents managing user accounts and prohibits platforms from using data from competitors for commercial gain. Enforcement falls to the Federal Trade Commission, with penalties for violations treated as unfair business practices.

Preserving Rural Housing Investments Act

Maddy summaryThis bill amends the tax code to clarify that the U.S. government and its agencies are excluded from the definition of "tax-exempt entity" when applying certain rules to stock held by government-sponsored enterprises (GSEs) like Fannie Mae and Freddie Mac. It directly affects how these GSEs manage their investments by preventing the federal government from being counted as a tax-exempt entity under specific provisions. The key change ensures that the tax-exempt status rules do not apply to U.S. government holdings in GSE stock, clarifying the legal framework for these financial institutions. This is a technical tax clarification with no direct provisions for rural housing programs, despite the bill's title.

A resolution expressing the sense of the Senate that the Secretary of Health and Human Services should withdraw a reduction in public notice and comment opportunities.

Maddy summaryThis resolution urges the Secretary of Health and Human Services (HHS) to withdraw a March 2025 Federal Register notice (90 Fed. Reg. 11029) that proposed reducing public comment periods for HHS regulations. It seeks to restore the previous standard of public participation in rulemaking, which HHS had followed for 54 years under the Administrative Procedure Act. The resolution emphasizes that public input is critical for fair policy decisions affecting millions of Americans through HHS regulations, including those impacting beneficiaries, state governments, and health service providers. As a non-binding resolution, it expresses the Senate’s position but does not alter HHS policy.
