For more detail
Choose one clear position: support, oppose, or amend. Then pick any reasons or personal context you want included. Modern Action uses that input and the bill context to draft a message you can review, edit, and send.
Congressional offices prioritize messages from their own constituents. Modern Action uses your address to route the generated message to your senators when that is the most relevant target for this bill.
The draft includes the bill number, your position, the reasons you selected, any personal context you added, and a direct ask such as voting yes, voting no, cosponsoring, opposing, or seeking changes. You stay in control because you review it before it sends.
This page is for understanding HALT Fentanyl Act, choosing whether you support it, oppose it, or want changes, and reviewing a generated message before it goes to Congress.
Modern Action keeps the action tied to the bill itself: what it would do, where it is in the process (became law), which office can still act, and what ask belongs in the message.
You are not starting from a blank form. Modern Action drafts the message around S.331, your stance, and the reasons you choose, then leaves the final review and edits to you.
