Jurisdiction source: House Rule X
How business reaches this committee
House Rule X gives this committee the subjects above. Each bill introduced in the House is referred to the committee whose Rule X jurisdiction covers its primary subject, and a bill that spans several subjects can go to more than one committee at once. This committee then decides whether to hold hearings, amend the text and report it to the floor.
Subcommittees
The committee divides its work among 5 subcommittees:
- Subcommittee on Energy
- Subcommittee on Environment
- Subcommittee on Investigations and Oversight
- Subcommittee on Research and Technology
- Subcommittee on Space and Aeronautics
