DEMAND Act of 2026

Maddy summaryThe DEMAND Act of 2026 requires the Secretary of Defense to incorporate projected demand from foreign military sales into key planning documents for the U.S. defense industrial base. This includes integrating these projections into industrial base assessments, munitions production plans, and sustainment strategies for major defense programs.

The primary goal is to expand production capabilities, stabilize critical suppliers, and encourage investment in essential production lines.

No Antisemitism in Education Act of 2026

Maddy summaryThe No Antisemitism in Education Act of 2026 requires schools and universities receiving federal funds to treat antisemitism with the same seriousness as other forms of discrimination prohibited by Title VI of the Civil Rights Act. Under this law, institutions must use the official definition of antisemitism found in a prior presidential executive order to investigate complaints and enforce their own policies. The bill explicitly states that these requirements do not violate free speech rights or override existing state laws, ensuring that Jewish students and staff are protected from harassment and exclusion on campus.

Stop Insider Trading Act

Maddy summaryHR 7008, the Stop Insider Trading Act, restricts Members of Congress, their spouses, and dependent children from purchasing certain investments like stocks in publicly traded companies. It requires 7-14 days' advance public notice before selling any such investment, including the sale date, description, and number of shares. Exceptions apply for work-related transactions (e.g., employer compensation) and reinvesting dividends. Violations trigger a fee of $2,000 or 10% of the investment’s value (whichever is greater), plus any net gain, paid from personal funds - not congressional allowances or campaign donations. The bill aims to prevent conflicts of interest by increasing transparency around congressional financial dealings.

Permanent CBDC Ban Act

Maddy summaryThis bill, titled the Permanent CBDC Ban Act, aims to permanently prohibit the Federal Reserve from issuing a central bank digital currency. It achieves this by amending the Federal Reserve Act to remove the specific legal authority that allows the Reserve to create such a digital currency. The legislation directly affects the Federal Reserve by stripping away its power to launch a digital version of the dollar. By deleting the relevant subsection of the law, the bill ensures that the Reserve cannot issue a CBDC in the future.

Shipbuilding Investment and Workforce Act

Maddy summaryThis bill creates a new tax incentive program to encourage investment in specific areas designated for maritime industries, such as shipyards and ports. It allows certain census tracts identified by the Secretary of Commerce, in consultation with federal officials, to be treated as qualified opportunity zones, which offers tax benefits to investors who put money into businesses operating within those areas. To qualify, the businesses must be directly involved in maritime activities like building or repairing vessels, and the program is limited to a maximum of 100 designated zones. The changes to the tax code will take effect after December 31, 2026, with the initial selection process for these zones beginning by July 1, 2027.

Small Unmanned Aircraft Systems Operational Test, Evaluation, and Training Corridor Act

Maddy summaryThis bill directs the Department of Defense to create designated airspace corridors specifically for testing and training small drones and the systems used to detect or neutralize them. These zones would allow military personnel to safely practice operating various drone technologies, such as sensors and autonomous software, alongside counter-drone measures like electronic warfare and directed energy weapons. The Secretary of Defense must identify suitable locations, potentially building new facilities or using existing ones, while consulting with other government agencies to ensure safety and address regulatory hurdles. Additionally, the bill requires the Pentagon to report to Congress within 90 days of establishing a corridor, providing details on its location, necessary resources, and any agreements with other federal partners.
