About KingSt.com

The Name

King Street in Alexandria, Virginia, has been the beating heart of Washington’s influence industry for decades. Trade associations, lobbying firms, and political consultancies line the boulevard just across the Potomac from Capitol Hill. If you want to shape legislation, you set up shop on King Street.

But America rejected the idea of a king over two centuries ago. The founders envisioned a government of the people — transparent, accountable, and answerable to citizens rather than courtiers.

KingSt.com exists to bridge that gap.

Our Mission

The same congressional intelligence that K Street firms charge thousands for should be accessible to everyone. KingSt.com makes it free.

We track all 535 voting members of Congress — 100 senators and 435 representatives — with detailed profiles, committee assignments, and contact information. Our Find My Rep tool lets you look up your legislators by ZIP code in seconds.

The goal is simple: put the data in your hands so you can hold your representatives accountable.

What We Offer

  • 535 Legislator Profiles — Every current senator and representative with biographical details, party affiliation, term dates, and office contact information
  • Committee Assignments — Which committees and subcommittees each member serves on
  • Find My Rep — Look up your senators and representative by ZIP code
  • Open Data — All our source data is public domain and freely available
