Defending America’s Future Elections Act

Maddy summaryS 1240, the Defending America’s Future Elections Act, repeals Executive Order 14248 (issued by President Trump in 2025), which the bill claims exceeded constitutional authority and threatened voter access. It prohibits federal funds from being used by the Department of Government Efficiency to access state voter registration lists, election records, or immigration databases for election-related purposes. The bill does not change existing voter registration rules (like the National Voter Registration Act of 1993) or election administration standards (like the Help America Vote Act of 2002). It directly affects federal agencies and departments by blocking funding for specific data access activities tied to the repealed executive order. This is a procedural bill focused on reversing a specific executive action, not creating new election policies.

Sanctioning Russia Act of 2025

Maddy summaryThe Sanctioning Russia Act of 2025 establishes a framework for imposing comprehensive sanctions on Russia if the President determines Russia is engaging in actions that undermine peace with Ukraine, such as refusing to negotiate a peace agreement, violating peace agreements, or planning another military invasion. If such a determination is made, the bill mandates blocking property of Russian officials and entities, prohibiting transactions with Russian financial institutions, increasing tariffs on Russian goods to at least 500% ad valorem, banning energy exports to Russia, and prohibiting purchases of Russian sovereign debt. It also imposes sanctions on countries that purchase Russian oil, uranium, or petroleum products, with duties of at least 500% on such goods. The bill requires the President to make determinations every 90 days and allows for termination of sanctions if Russia ceases harmful actions and enters a peace agreement with Ukraine, with immediate reimposition if Russia resumes those actions.

Paying a Fair Share Act of 2025

The bill does not apply to corporations or estates/trusts under the defined rules.

Savings Opportunity and Affordable Repayment Act

Maddy summaryThe Savings Opportunity and Affordable Repayment Act creates a new income-driven repayment plan for federal student loan borrowers, replacing the current Pay As You Earn and Income Contingent Repayment plans. Under this plan, monthly payments are calculated as 5% of income above 250% of the federal poverty line (with a minimum $0 or $10 payment), and 50% of each payment reduces principal while interest accrues only on unpaid balances. Borrowers qualify for full loan forgiveness after 120 payments (10 years) for undergraduate-only loans or 180 payments (15 years) for other eligible loans. The plan applies to borrowers with eligible federal loans and takes effect 180 days after enactment.

A joint resolution proposing an amendment to the Constitution of the United States relating to contributions and expenditures intended to affect elections.

Maddy summarySJRES 43 proposes a constitutional amendment allowing Congress and state governments to set reasonable limits on campaign contributions and expenditures intended to influence elections. It would permit distinctions between individuals and corporations, including the potential prohibition of corporate spending in political campaigns.

If ratified by three-fourths of state legislatures, this change would directly affect candidates, political committees, and organizations that spend money to influence elections.
