In both the House and Senate, any number of members may join in introducing a single bill or resolution. The first member listed is the sponsor of the bill, and all members' names following his or hers are the bill's cosponsors. Many bills are introduced under the name of the chairman of the committee or subcommittee with jurisdiction over the measure. All appropriations bills fall into this category. A committee frequently holds hearings on a number of related bills and may agree to one of them or to an entirely new bill.
