Our Data

The Lobby is built on public information, processed with modern tools.

We believe you should know where our data comes from. This page lists the sources behind every bill, vote, summary, and member profile on the site — and the third-party services we rely on to deliver newsletters to subscribers.

Where a source is publicly available, we link to it directly so you can verify any claim we make or read the original material yourself.

Legislative Data

Every bill, action, sponsor, committee referral, and roll call vote that appears on The Lobby is sourced from official records published by the U.S. Congress. We ingest these records on a regular schedule, store them in our own database, and link back to the original source wherever possible.

• Congress.gov API

  The official Library of Congress API. Our primary source for bill text, summaries, sponsors and cosponsors, committee referrals, bill actions, related bills, subject tags, and House roll call votes.

• Congress.gov

  The public-facing companion to the API above. Where we link readers when they want to verify a citation or read a bill in its original form.

• U.S. Senate — Roll Call Votes

  The Senate publishes its own roll call vote records as XML feeds. We use these directly for Senate vote tallies and per-senator positions.

• House.gov — Member Directory

  Reference source for House member rosters and district information. Used to cross-check legislator records returned from the Congress.gov API.

• @unitedstates/congress-legislators

  An open, community-maintained dataset of current and historical members of Congress, including biographical details, terms of service, and committee assignments. We use it to enrich and verify the legislator records we ingest from official sources.

Subscriber Data

When you sign up for a newsletter, you give us your email address and select the topics you’re interested in. We use that information to decide which bills to include in your personalized newsletter and to record your subscription preferences. We do not sell subscriber data, and we maintain durable opt-in and opt-out records as required by law.

• Provided directly by subscribers

  Email address, selected interest topics, newsletter engagement (opens, clicks), and opt-in / opt-out history. Full detail is available in our Privacy Policy.

Email Delivery

Newsletters are delivered through a third-party email service provider. The provider receives the recipient’s email address and the rendered newsletter content in order to deliver it, and reports back delivery, open, and click events.

• SendGrid (Twilio)

  Our email service provider. Handles sending, bounce processing, unsubscribe link handling, and delivery / engagement event reporting.

How We Handle Corrections

Legislative records change. Bills get amended, votes get recorded after the fact, and occasionally a source we rely on publishes a correction of its own. When that happens, we re-ingest the updated record and our pages update automatically.

If you spot something that looks wrong — a missing vote, a misattributed sponsor, a summary that doesn’t match the underlying bill — please let us know at hello@thelobbynews.com.
