Modern Action explains legislation in plain English, helps you choose whether to support, oppose, or ask for changes, and drafts a message tied to the bill, your stance, and the elected officials who can act on it.
DEFUND Act of 2025 is a Senate bill in committee. The latest recorded action: Read twice and referred to the Committee on Foreign Relations.
Latest action on S. 669: Read twice and referred to the Committee on Foreign Relations.
Who this affects: This bill would directly change how the U.S. interacts with the rest of the world on issues like security, health emergencies, and humanitarian aid. It would also affect thousands of international workers and diplomats based in the U.S.
Why this matters: The U.S. has been a founding member of the United Nations since 1945 and is its largest funder. Leaving would be one of the biggest shifts in American foreign policy in decades. It would affect how the U.S. works with other countries on security threats, disease outbreaks, humanitarian crises, and international rules that touch everyday life like air travel and shipping standards.
You do not have to start with a blank letter. Modern Action turns the bill, your position, and the relevant congressional context into a message you can edit and send. The goal is to make contacting Congress clear, specific, and useful without forcing you to parse bill text or figure out the right office on your own.
