In committee · Indiana House · Co-sponsor
To amend title XI of the Social Security Act to ensure nursing facilities report information on medical directors of such facilities.

Maddy summaryHR 177 requires nursing facilities to report specific information about their medical directors to the federal government. This affects all nursing facilities participating in Medicare and Medicaid, as they must include this data in required reports starting 90 days after updated regulations are published. The bill mandates that the Secretary of Health and Human Services issue these updated regulations within two years, making the reported medical director information publicly available on the Nursing Home Compare website six months after the regulations publish. This creates a new data point for the public to review regarding nursing facility leadership.

Sustainable International Financial Institutions Act of 2024

Maddy summaryThis bill requires U.S. representatives at 12 major international financial institutions (including the World Bank, Asian Development Bank, and Inter-American Development Bank) to vote against fossil fuel projects and support clean energy transitions. It mandates that U.S. contributions to these institutions be reduced if they fund new fossil fuel capacity (like oil/gas projects or pipelines), with the withheld funds held in an escrow account until institutions stop such funding. The bill also prohibits U.S. agencies (like USAID and the Export-Import Bank) from providing any foreign assistance for fossil fuel activities or related infrastructure. These changes directly affect how U.S. taxpayer funds are allocated to global development projects managed by these institutions.

Whale CHARTS Act of 2024

Maddy summaryThe Whale CHARTS Act of 2024 requires the U.S. Commerce Secretary (via NOAA) to create detailed, high-resolution maps showing where baleen whales and sperm whales live, feed, calve, and migrate in U.S. waters. These maps must include current and future habitat data, using tools like satellite imagery and drones, and be made available in formats that integrate with ship navigation systems to help vessels avoid whale areas. The bill also mandates regular surveys of understudied whale populations and requires annual reports to Congress on progress. It authorizes $2 million yearly for mapping and $1 million for surveys through 2029, with funding to support research on knowledge gaps. The law directly affects commercial and recreational vessels through navigation system updates and marine researchers through data collection requirements.

Promoting United States Leadership in Standards Act of 2024

Maddy summaryThis bill directs the National Institute of Standards and Technology (NIST) to enhance U.S. leadership in developing global technical standards for artificial intelligence and emerging technologies. It requires NIST to provide Congress with a briefing on standards opportunities, create a public web portal listing international standards efforts and participation opportunities, and establish a 5-year pilot program to fund U.S.-hosted standards meetings. The pilot offers grants (up to 50% of hosting costs, capped at $5 million total) to eligible organizations developing AI/tech standards or hosting such standards bodies. This directly affects federal agencies (which must report their participation), U.S. industry groups, and standards organizations seeking to host international meetings in the United States.
