How business reaches this committee
This is a joint committee, so its membership is drawn from both the House and the Senate. Joint committees study, oversee and publish. Bills are not referred to them and they do not report legislation to either floor, so their influence runs through the reports and analysis they produce for the committees that do.
Subcommittees
The committee has no subcommittees. Every hearing, markup and vote happens in full committee, which keeps the whole membership on the same set of questions.
Joint committees are small by design, with members drawn from both chambers. Working in full committee keeps the House and Senate members in the same room, which is the reason for having a joint committee in the first place.
Who serves on it
10 members sit on the committee: 6 Republicans and 4 Democrats. That gives the majority 6 of the 10 seats. Mike Crapo is the chairman. Jason Smith is the vice chairman. They come from 10 states and districts between them.
Following its work
Hearing notices, markup schedules, witness lists and published reports live on the committee’s own site, linked at the top of this page. The full member list below links to each member’s page here, with contact details and the seat they hold.
