Each story starts with an event, traces the bills and roll-call votes that followed, and ends with the law. Open any vote to see every member of Congress, their party and state, and how they voted.
How it works
- The event. What happened and when, from primary and official sources.
- The votes. Each recorded vote in the House and Senate, with the result and the split by party.
- The legislators. Every member's vote, searchable by name, party, state and how they voted.
These are the first entries in a growing library. More events, laws and every recorded vote since 1789 will be added over time.
