Following introduction in the House or Senate, a bill, resolution or other measure is normally referred to one or more committees in that body.
In the House, measures are referred by the Speaker primarily to one committee, with additional referrals to other committees that also maintain jurisdiction over the matter covered by that measure. The primary committee to which a measure is referred is called the “lead committee.”
For additional information see:
A document by the House Rules Committee that describes each “standing” House committee’s jurisdiction, which is based on the broad jurisdictional outlines provided by House Rule X and supplemental precedents and informal agreements among committees over the years.

In the Senate, measures generally are referred to a single committee based on “the subject matter which predominates.” However, by unanimous consent, the Senate may permit multiple referrals for measures that cross more than one committee’s jurisdictional boundaries. For additional information see:
