Each committee is chaired by a member of the majority party. Almost all bills are first referred to a committee, and ordinarily the full House cannot act on a bill until the committee has “reported” it for floor action. There are approximately 20 standing (permanent) committees, organized mainly around major policy areas, each having staffs, budgets, and subcommittees. They may hold hearings on questions of public interest, propose legislation that has not been formally introduced as a bill or resolution, and conduct investigations.
