## What it is
A curated open dataset of United States Congress members from 1789 to present, plus committees, committee membership, and presidents/vice presidents, published in YAML, JSON, and CSV. It is maintained by the @unitedstates community under a CC0 public-domain license.

## Use cases
- get a list of all current US senators and representatives
- look up historical members of Congress since 1789
- find committee memberships for Congress
- download congressional data as YAML or JSON for analysis
- find social media accounts of members of Congress
- get data on US presidents and vice presidents

## When to choose
- you need structured, public-domain data on US legislators or committees
- you want machine-readable formats (YAML/JSON/CSV) with no licensing restrictions
- you need historical coverage back to 1789

## When to avoid
- you need real-time voting records or bill data (use ProPublica/US Congress API instead)
- you need a GUI or API service rather than raw data files
- you need non-US legislative data

## Facets
- artifact type: dataset
- maturity: active
- function: data-science, developer-tools
- domain: e-government, data-science, apis
- platform: cross-platform
