Congress · Stage 01

Idea & Introduction

A policy idea is drafted into legislative language and formally introduced by a member of the House or Senate.

After introduction, the bill receives a number, is entered into the congressional record, and is normally referred to the committee or committees with jurisdiction over its subject.

Key idea

A proposal does not become law simply because it is introduced. Introduction begins the formal legislative process.

Veto Return to Congress

No actionTiming determines the result

The 10-day constitutional period and congressional adjournment matter.

Important Distinction

Passing a bill and reaching a final vote are different questions.

In the Senate, ordinary legislation can generally pass by a simple majority once a final vote occurs, but Senate procedure may require a larger coalition to end debate and reach that vote. Understanding procedure is essential to understanding why legislation can stall even when a numerical majority supports it.
