How do I find legislation that a member of Congress sponsored or cosponsored?

The representative or senator who introduces a bill for consideration is termed the bill’s sponsor. In addition to the sponsor, a bill can have multiple cosponsors, who sign onto a bill to demonstrate their support. The sponsor and cosponsor(s) are listed on the first page of a bill, before its main text. Researchers can determine the sponsor and cosponsors of a particular bill by opening a bill information page on Congress.gov and selecting the “Cosponsors” tab. For example, the cosponsors information for 116 H.R. 276 lists both a sponsor and 57 cosponsors, 20 of whom were original cosponsors of the bill. Congress.gov also has a feature where researchers can browse sponsors and cosponsors to bills and amendments in the House and Senate by Congress.

For further information about bill sponsorship and cosponsorship, researchers can consult these online resources:
