Where is it in the process, and what happens next?

The latest action on file does not map to a stage Civibrief recognizes, so the page will not name one. The record's own words are the reliable fact here.

How likely is it to become law?

Civibrief does not forecast outcomes and this page has no opinion about this one. What the record supports is a base rate, which is a fact about the whole pile, not a prediction about this measure.

In the 118th Congress (2023-24), 274 of the 16,565 bills and joint resolutions introduced became law, about 1.7 percent. That count covers every measure at every stage, including the many that never left committee.

This one has no outstanding steps listed above.

Has anyone actually voted on it?

Yes. 1 recorded roll-call vote cites this measure, listed further down this page with every member's position.

Who is behind it?

Roger Wicker (R-MS) introduced it on June 15, 2026. No cosponsors are recorded.

Cosponsoring is a formal signature on the text. It is not a commitment to vote for the measure, it does not bind anyone's party, and a long list of cosponsors is a measure of attention rather than of prospects.

How long has it been in play?

It was introduced on June 15, 2026, 87 days ago. The most recent recorded action was 45 days ago, on July 27, 2026.

Measures do not carry over. Anything the 119th Congress has not finished by January 3, 2027 dies when the term ends, and has to be introduced again from the start in the next Congress.

Every answer above is assembled from this measure's own record on Congress.gov and from published counts of what Congress has passed before. Civibrief does not predict outcomes and takes no position on any measure.
